Since you oft can't be sure what caused the 503 error in whatever given state of affairs, you lot'll demand to go about troubleshooting it methodically. The following six sections each cover a potential fix, aimed at resolving the different potential root causes.
After each step, take a moment to render to your website and see if the 503 fault is gone. If it is, you've successfully fixed the outcome. If not, proceed on to the next step in the process.
1. Temporarily Deactivate Your WordPress Plugins
I of the nigh common causes of the 503 error in WordPress is plugin compatibility issues. To determine if that'southward what'southward happening, you'll need to disable all of your site's plugins.
Since the 503 fault prevents you from accessing the WordPress admin area, yous'll need to apply an FTP client for this pace. If you don't take ane set up, we recommend FileZilla.
Once your FTP client is ready, connect to your website through it and navigate to your WordPress root folder. In case you can't find information technology, it's usually called public_html, html, public, www, or your site's name. If you're a Kinsta client, information technology's your public folder.
Open that binder, and navigate to the wp-content directory. Inside, y'all'll see a folder called plugins, which contains individual subdirectories for each of the plugins installed on your site (both active and inactive).
What you're going to do now is correct-click on the plugins binder, and rename it to something else. We recommend plugins.former or plugins.deactivated, so you tin easily recognize it later.
WordPress will now not be able to notice any of your plugins. When that happens, it volition automatically disable those plugins.
At present, endeavour accessing your WordPress dashboard. If the 503 error is gone, so y'all tin can assume that one of your plugins was the culprit. All you lot take to do is figure out which ane was at fault.
Return to the wp-content directory, and rename your original plugins folder correctly. Then, you'll need to disable each of your plugins i by 1, until you find the culprit.
To do this, open up the wp-content/plugins directory. Within, you'll notice one binder for each of your plugins. The process you're going to follow is much the same every bit before:
- Start with the first folder, and rename information technology to annihilation you like.
- Check your website to see if the fault is gone.
- If information technology isn't, return the plugin folder from the previous step to its original proper noun.
- Move on to the next plugin on your list, repeating the above steps.
This process can take a while if you have a lot of plugins, merely it'southward vital to check each plugin in plow. If at whatever point you lot place the plugin that'southward causing the error, you can uninstall information technology or replace it with another tool.
If yous make it to the finish of these steps without finding a solution, you lot tin can move on to the next stage of troubleshooting.
two. Deactivate Your WordPress Theme
At present that y'all've ruled out your plugins every bit the cause of the 503 error, it'southward time to do the same with your active theme. In fact, your theme could as well exist creating compatibility issues.
Unfortunately, the process doesn't work the same equally above. WordPress won't revert to the default theme if simply rename the theme binder, y'all would terminate up with an mistake similar "The theme directory "theme name" does not be." Or if you endeavour to rename the entire theme directory folder, you lot stop upward with "Error: The themes directory is either empty or doesn't exist. Please check your installation."
Therefore, you need to admission your WordPress database by logging into phpMyAdmin. If you're a Kinsta client, this can be found inside the "Info" section of the MyKinsta dashboard.
Click into the "wp_options" table, then click on the "Search" tab. You lot volition desire to search under the "option_name" for template.
Under the "option_value" cavalcade you will encounter the current proper name of your theme. Change this to ane of the default themes, such every bit "twentynineteen."

Check your website again to see if this has stock-still the error. If information technology did, it simply means it'south a problem with your WordPress theme and you might want to effort reinstalling it or reverting to your most contempo backup.
three. Temporarily Disable Your Content Delivery Network (CDN)
Sometimes, the 503 fault will show up not because of a problem on your website, merely considering of your Content Delivery Network (CDN). If y'all're using a CDN, a quick way to figure out if that's the case is to temporarily disable it.
Every CDN should include some feature that enables you lot to suspension its services. If you're on Kinsta, you can disable your Kinsta CDN by navigating to CDN → "Disable CDN" inside your MyKinsta dashboard:
The process y'all need to follow may be different depending on which CDN you're using. Cloudflare has as well been known to cause 503 errors sometimes. If you tin't discover the pick to suspension yours, cheque out your service'due south knowledge base, which will usually contain detailed instructions.
If y'all don't use a CDN or find that pausing your service doesn't help with your event, in that location are still a few more fixes to try. Do remember to reactivate your CDN before moving on.
iv. Limit the WordPress 'Heartbeat' API
The WordPress Heartbeat is an API built into WordPress, which the platform uses for auto-saving content, showing you plugin notifications, letting you lot know when someone else is working on a post you're trying to access, and more than.
Just like a regular heartbeat, the API works in the background with a loftier frequency so that it doesn't miss anything. Equally you might imagine, this API consumes server resources. Commonly, that's not a problem but in some cases, it may lead to a 503 error if your server tin't handle the load.
The quickest way to determine if the Heartbeat API is at the center of your bug is to temporarily disable it. To do that, connect to your WordPress website via FTP again, and so open your current themes folder and look for the functions.php file within:
Correct-click on the file and select the View/Edit option, which will open it using your local text editor. One time it'southward open up, you'll need to add together the post-obit code snippet within:
add_action( 'init', 'stop_heartbeat', 1 ); role stop_heartbeat() { wp_deregister_script('heartbeat'); } Those 3 lines of code tell WordPress to disable the Heartbeat API. Save the changes to the functions.php file, close information technology, and try to admission your website again.
If the 503 fault is gone, you'll know that the API was the problem. Disabling it altogether removes a lot of useful functionality, even so. Instead, we recommend that you 'slow down' the Heartbeat, and then that information technology doesn't cause problems.
The easiest way to do that is past installing the Heartbeat Control plugin. Activate the plugin and navigate to the Settings > Heartbeat Control section. Look for the Modify Heartbeat options, and drop the frequency to the lowest possible number:
Relieve the changes to your settings and render to the functions.php file y'all tweaked a while back. For the higher up changes to work, yous'll demand to remove the string of lawmaking you added before and save your changes to the file.
At this stage, the 503 error should be gone if the Heartbeat API was the trouble. If information technology isn't, then it's time to try something unlike.
5. Increase Your Server's Resource
If the 503 error is still occurring despite all your attempts to set up it and so far, then in that location's a good take a chance the problem might be due to a lack of server resources. That is to say, you lot'll need to upgrade your hosting plan to see if that fixes the issue.

The support squad should be able to aid you work out the cause and propose you on whether you need to upgrade your program or not.
half dozen. Review Your Logs and Enable WP_DEBUG

This tin can assist you speedily narrow downwardly the issue, especially if information technology's resulting from a plugin on your site.
If your host doesn't accept a logging tool, you can also add together the following code to your wp-config.php file to enable logging:
define ( 'WP_DEBUG' , true ) ; define ( 'WP_DEBUG_LOG' , truthful ) ; define ( 'WP_DEBUG_DISPLAY' , simulated ) ; The logs are typically located in the /wp-content directory. Inside it, look for a file called debug.log and open it up.
Others, similar here at Kinsta might accept a dedicated folder called "logs".
Interpreting your debug log tin can be a flake intimidating but it'south non as difficult to read every bit you might imagine. In a nutshell, the log contains each mistake that pops upwards on your site in chronological order. It shows which file caused each error, besides equally which specific lines of lawmaking were involved.
Beware: you're not going to observe direct references to the 503 error within your log. Even so, if all else fails, it tin can point y'all in the right direction past showing you what files are causing problems. That mode, you'll know where to focus your efforts next.
