How to Fix the 503 Error in WordPress
Since you canâ€™t automatically determine what caused the 503 error, youâ€™ll have to troubleshoot methodically. The subsequent six sections serve as a possible fix, aimed toward resolving the potential root causes.
Briefly Deactivate Your WordPress Plugin
One of the most common reasons for the 503 Error in WordPress is module similarity issues. To determine whatâ€™s happening, disable all of your siteâ€™s plugins.
Since the 503 error prevents you from accessing the WordPress admin space, use an FTP client for this step. If you donâ€™t have one created, we tend to suggest FileZilla.
When your FTP customer is readied, interface with your site and explore to your WordPress root organizer. Itâ€™s typically referred to as public_html, html, public, www, or your siteâ€™s name. If youâ€™re a Kinsta shopper, itâ€™s your public folder.
Open that folder, and navigate to the wp-content directory. Inside, youâ€™ll see a folder referred to as plugins that contain individual subdirectories for each of the plugins in on your website (both active and inactive).
Right-click the plugins folder, and rename it. We suggest plugins.old or plugins.deactivated
WordPress is unable to notice any of your plugins and will disable those plugins.
Return to the WP-Content registry, and rename your unique modules organizer. Disable your plugins one by one, till you discover the erroring plugin.
To do this, open the wp-content/plugins directory. Inside, youâ€™ll notice one folder for each plugin. Start with the primary folder, and rename it. Check your website to determine if the error is gone. If it isnâ€™t, move on to subsequent plugin on your list, repetition the on top of steps.
This method will take a minute, however itâ€™s very important to examine every plugin successively. If you determine the plugin thatâ€™s inflicting the error, uninstall or replace it with another tool.
Deactivate Your WordPress Theme
Now that youâ€™ve ruled out your plugins asÂ the reason for the 503 error, itâ€™s time to look intoÂ your active theme.Â
WordPress will not revert to the default theme by renamingÂ the theme folder.Instead, access your WordPress information through phpMyAdmin
Click into the â€œwp_optionsâ€ table, then the â€œSearchâ€ tab. You may need to look to the â€œoption_nameâ€ guide.
Under the â€œoption_valueâ€ column you will see this name of your theme. Change the theme to one of the default themes, such as â€œtwenty nineteen.â€
Check your web site once more to see if the error was resolved.Â Â
Temporarily Disable Your Content Delivery Network (CDN)
Sometimes, the 503 error can show up as a result ofÂ a drag on your website to your Content Delivery Network (CDN). The process is different depending on the CDN youâ€™re using. Cloudflare has been known to cause 503 errors.
If you donâ€™t use a CDN or you are unable to pauseÂ your service, there are still additional ways to troubleshoot.Â
Limit the WordPress â€˜Heartbeatâ€™ API
The WordPress Heartbeat is an API engineered into WordPress that the platform uses for auto-saving content, showing plugin notifications, recognizingÂ if another person is on a post youâ€™re attempting to access.
The API works in the background at a high frequency so it doesnâ€™t miss anything. The API consumes server resources. In some cases, it results in a 503 error if your server canâ€™t handle the load.
The fastest way to determine if the problem is the Heartbeat API is to quickly disable it. To do that, connect with your WordPress web site via FTP, open your current themes folder and look for the functions.php file within:
Disable the Heartbeat API. Save the changes to the functions.php file and access your web site.
Disabling the API altogether removes helpful practicality. Instead, we suggestÂ simply â€˜slowing downâ€™ the Heartbeat, so it doesnâ€™t cause issues.
The easiest thanks to do this is through the Heartbeat management plugin.Navigate to Settings > Heartbeat control section. search for the Modify Heartbeat choices, and drop the frequency number:
Increase Your Serverâ€™s Resources
