How to Fix 503 Service Unavailable Error
Deactivating all plugins in WordPress
As you know, all plugins are PHP scripts, so the first thing you need to do is deactivate all of them.
When this error happens, you can’t access or log in to the admin dashboard area. Therefore, let’s connect your website with an FTP client or File Manager in cPanel. After connecting, you need to go to /wp-content/ folder to change the names of plugins into plugins-old.
In the next step, you just need to generate a new folder, then name it plugins.
Now, let’s come back to your WordPress site that the error has been addressed all not. If this error is fixed, this means a plugin that is installed on your site causes this error. Thus, you have to find which plugin causes the issue.
In order to do that, let’s switch back to File Manager or FTP client. Then, you need to access the /wp-content/ folder. Next, simply delete the empty plugin folder. After deleting the folder, let’s alter the plugins-old folder into plugins. When you do that, you can make all installed plugins available but deactivated.
Now, all you need to do is go to the WordPress admin dashboard and access the plugins page. Next, simply activate the plugins one by one, then open the different pages of the website until you find which plugin causes the error.
If this way can’t help you solve this issue, let’s follow the next method.
Switching to a default WordPress theme
If this error is not generated by the plugin, let’s check the theme in use. Now, we will switch to a default WordPress theme. This means you will deactivate the theme you are utilizing.
First of all, you simply connect your website with an FTP client or File Manager in cPanel. Then, let’s find /wp-content/themes/ folder. Now, all you need to do is seek the WordPress that is currently activated, download it to backup.
After that, let’s delete it and utilize a default theme. Now, let’s check again whether the error is fixed or not.
