One of the well-nigh common causes of the 503 error in WordPress is plugin compatibility bug. To make up one's mind if that'southward what's happening, y'all'll need to disable all of your site'south plugins.
Since the 503 error prevents you from accessing the WordPress admin area, you lot'll need to utilize an FTP customer for this stride. If you don't accept one ready, we recommend FileZilla.
One time your FTP client is ready, connect to your website through information technology and navigate to your WordPress root binder. In example you lot can't find it, it'southward usually called public_html, html, public, www, or your site's name. If you're a Kinsta client, it's your public folder.
Open that folder, and navigate to the wp-content directory. Within, you'll come across a folder chosen 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 folder, and rename it to something else. We recommend plugins.old or plugins.deactivated, so you lot can easily recognize it later.
WordPress will now not be able to find any of your plugins. When that happens, information technology will automatically disable those plugins.
Now, try accessing your WordPress dashboard. If the 503 mistake is gone, then you lot can assume that i of your plugins was the culprit. All you have to do is figure out which one was at fault.
Return to the wp-content directory, and rename your original plugins folder correctly. Then, you'll demand to disable each of your plugins ane by one, until you find the culprit.
To do this, open the wp-content/plugins directory. Inside, you'll find i folder for each of your plugins. The process you're going to follow is much the same every bit before:

- Check your website to see if the error is gone.
- If information technology isn't, return the plugin folder from the previous step to its original proper noun.
- Move on to the side by side plugin on your listing, repeating the in a higher place steps.
This process can take a while if you accept a lot of plugins, just it'southward vital to bank check each plugin in turn. If at any point you place the plugin that's causing the error, you can uninstall it or replace it with some other tool.
If yous arrive to the finish of these steps without finding a solution, you tin can move on to the adjacent stage of troubleshooting.
2. Deactivate Your WordPress Theme
Now that yous've ruled out your plugins as the crusade of the 503 error, it'south time to do the same with your agile theme. In fact, your theme could also exist creating compatibility bug.
Unfortunately, the procedure doesn't work the same every bit to a higher place. WordPress won't revert to the default theme if simply rename the theme folder, you would finish up with an error like "The theme directory "theme name" does non exist." Or if you try to rename the entire theme directory folder, you cease up with "Error: The themes directory is either empty or doesn't be. Please check your installation."

3. Temporarily Disable Your Content Commitment Network (CDN)
Sometimes, the 503 fault volition show up not because of a problem on your website, simply considering of your Content Delivery Network (CDN). If you lot'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 to interruption its services. If you're on Kinsta, yous tin can disable your Kinsta CDN by navigating to CDN → "Disable CDN" inside your MyKinsta dashboard:
The process you need to follow may be different depending on which CDN you're using. Cloudflare has also been known to cause 503 errors sometimes. If you can't find the selection to pause yours, check out your service's knowledge base, which volition usually contain detailed instructions.
If yous don't apply a CDN or detect that pausing your service doesn't help with your issue, there are still a few more fixes to try. Do retrieve to reactivate your CDN before moving on.
4. Limit the WordPress 'Heartbeat' API

If the 503 fault is gone, yous'll know that the API was the trouble. Disabling it birthday removes a lot of useful functionality, however. Instead, we recommend that y'all 'deadening downwardly' the Heartbeat, so that it doesn't crusade issues.
The easiest way to do that is by installing the Heartbeat Control plugin. Activate the plugin and navigate to the Settings > Heartbeat Command section. Look for the Modify Heartbeat options, and drop the frequency to the lowest possible number:
Save the changes to your settings and return to the functions.php file you tweaked a while back. For the above changes to work, you'll need to remove the string of lawmaking you lot added before and save your changes to the file.
At this stage, the 503 error should exist gone if the Heartbeat API was the problem. If it isn't, then information technology's time to effort something unlike.
