The 503 (Service Unavailable) status code indicates that the server is currently unable to handle the request due to a temporary overload or scheduled maintenance, which volition likely be alleviated later some delay. The server MAY send a Retry-After header field to advise an appropriate amount of time for the client to wait before retrying the asking.
When you encounter the 503 error, it means that the server in question is unavailable. That could exist because it's too busy, for example, or it'southward under maintenance. Dissimilar other similar error codes, 503 signifies that your website is online and running, but can't be reached at the present moment.
What'due south so vexing well-nigh this particular error is that it barely gives you any information to proceed. Most of the time, it just shows up with a "Service temporarily unavailable" message.

How to Ready the 503 Error in WordPress (vi Steps)
Since you often tin't be sure what caused the 503 error in whatsoever given situation, y'all'll need to get about troubleshooting information technology methodically. The following six sections each cover a potential ready, aimed at resolving the different potential root causes.
Later on each stride, have a moment to return to your website and see if the 503 error is gone. If it is, you lot've successfully fixed the issue. If not, continue on to the adjacent step in the procedure.
i. Temporarily Conciliate Your WordPress Plugins
One of the most mutual causes of the 503 error in WordPress is plugin compatibility issues. To determine if that'southward what's happening, you'll demand to disable all of your site'southward plugins.
Since the 503 fault prevents you from accessing the WordPress admin area, you'll demand to utilise an FTP client for this stride. If you lot don't have 1 set up, we recommend FileZilla.
One time your FTP client is set, connect to your website through information technology and navigate to your WordPress root folder. In case yous can't observe it, it's usually chosen public_html, html, public, www, or your site'due south proper name. If yous're a Kinsta customer, it'due south your public binder.
Open that folder, and navigate to the wp-content directory. Inside, y'all'll encounter a folder called plugins, which contains private subdirectories for each of the plugins installed on your site (both active and inactive).
What yous're going to exercise now is right-click on the plugins folder, and rename it to something else. We recommend plugins.former or plugins.deactivated, and then you tin easily recognize information technology later.
WordPress volition now not be able to discover any of your plugins. When that happens, it volition automatically disable those plugins.
Now, try accessing your WordPress dashboard. If the 503 fault is gone, then you lot can assume that one of your plugins was the culprit. All you have to do is figure out which ane was at error.
Return to the wp-content directory, and rename your original plugins folder correctly. Then, y'all'll demand to disable each of your plugins one by 1, until y'all detect the culprit.
To do this, open up the wp-content/plugins directory. Within, you'll find 1 folder for each of your plugins. The process you're going to follow is much the same as earlier:
- Start with the first binder, and rename information technology to anything you lot like.
- Check your website to see if the mistake is gone.
- If information technology isn't, render the plugin binder from the previous step to its original name.
- Move on to the side by side plugin on your list, repeating the higher up steps.
This procedure can accept a while if y'all have a lot of plugins, but information technology's vital to check each plugin in plough. If at any point you place the plugin that'southward causing the fault, y'all can uninstall it or supersede information technology with another tool.
If yous make information technology to the end of these steps without finding a solution, yous can motility on to the next stage of troubleshooting.
two. Conciliate Your WordPress Theme
At present that you've ruled out your plugins as the cause of the 503 mistake, it's time to do the aforementioned with your active theme. In fact, your theme could as well be 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 folder, you would end up with an error like "The theme directory "theme proper name" does not exist." Or if you try to rename the entire theme directory binder, you stop up with "Mistake: The themes directory is either empty or doesn't be. Delight bank check your installation."
Therefore, y'all demand to access your WordPress database by logging into phpMyAdmin. If you're a Kinsta client, this can be found within the "Info" section of the MyKinsta dashboard.
Click into the "wp_options" table, so click on the "Search" tab. Yous will want to search under the "option_name" for template.
Nether the "option_value" cavalcade yous will see the current name of your theme. Modify this to i of the default themes, such as "twentynineteen."

3. Temporarily Disable Your Content Delivery Network (CDN)
Sometimes, the 503 mistake will show up not considering of a problem on your website, but 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 to pause its services. If you're on Kinsta, you can disable your Kinsta CDN by navigating to CDN → "Disable CDN" within your MyKinsta dashboard:
The process you need to follow may be different depending on which CDN you lot're using. Cloudflare has also been known to crusade 503 errors sometimes. If yous can't find the option to interruption yours, cheque out your service'south noesis base of operations, which will normally contain detailed instructions.
If you don't use a CDN or notice that pausing your service doesn't help with your issue, there are yet a few more fixes to try. Practice remember to reactivate your CDN before moving on.
4. Limit the WordPress 'Heartbeat' API
The WordPress Heartbeat is an API built into WordPress, which the platform uses for motorcar-saving content, showing you plugin notifications, letting you know when someone else is working on a post y'all're trying to access, and more.
Just similar a regular heartbeat, the API works in the background with a loftier frequency so that it doesn't miss anything. Every bit you might imagine, this API consumes server resources. Usually, that's not a problem merely in some cases, it may lead to a 503 mistake if your server can't handle the load.
The quickest way to determine if the Heartbeat API is at the center of your problems is to temporarily disable it. To exercise that, connect to your WordPress website via FTP once again, and then open up your current themes folder and await for the functions.php file within:
Right-click on the file and select the View/Edit option, which will open it using your local text editor. Once it'south open, you'll need to add the post-obit code snippet within:
add_action( 'init', 'stop_heartbeat', 1 ); function stop_heartbeat() { wp_deregister_script('heartbeat'); } Those three lines of lawmaking tell WordPress to disable the Heartbeat API. Save the changes to the functions.php file, close it, and endeavor to access your website again.
If the 503 error is gone, you'll know that the API was the trouble. Disabling information technology altogether removes a lot of useful functionality, however. Instead, nosotros recommend that you lot 'slow downward' the Heartbeat, so that it doesn't cause problems.
The easiest way to do that is by installing the Heartbeat Control plugin. Actuate the plugin and navigate to the Settings > Heartbeat Control section. Expect for the Modify Heartbeat options, and driblet 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 piece of work, you'll need to remove the cord of code 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 problem. If it isn't, then it's fourth dimension to effort something different.

In a nutshell, the log contains each error that pops up on your site in chronological order. It shows which file caused each error, too as which specific lines of code were involved.
Beware: you're not going to find direct references to the 503 mistake within your log. Still, if all else fails, it tin can bespeak you in the correct direction by showing you what files are causing problems. That way, you'll know where to focus your efforts adjacent.
