How to disable Plugins: As a WordPress webmaster, you may encounter that you cannot access the WordPress dashboard anyway. You suspect that it may be caused by some WordPress plugins. At this time, what do you do if you want to disable all plugins?
Method 1: Operation via FTP or file management
As the website admin panel is no longer accessible, we can only disable the WordPress plugin through FTP or the server file manager. The specific method is as follows:
Access your site’s wp-content directory using FTP or a file manager. Rename The plugins folder to something else, such as “plugins123”, so that you can disable all plug-ins.



How to Find Which Plugin Cause Problem?
If you want to continue to find plugins that may have problems, follow these steps:
1. Try to yourwebsite.com/wp-admin/
access and log in to the admin panel through the URL. If this solves the problem, it means that there is a problem with your plugin. All we need to do now is find the exact culprit.
2. Change the “plugins123” folder back to the original name plugins. This way, WordPress can re-access your plugins, but all plugins are still inactive. So don’t worry.
3. Log in to your WordPress dashboard and go to Plugins> Installed Plugins, activate one plugin at a time, and refresh the website. If a 503 error occurs after activating a plugin, it means that this plugin is causing an error.
Disable Plugins Through Ftp or File Manager:
Via FTP or file manager, visit the wp-content>plugins directory and delete the plugins.
Method 2: Disable plugins through the database
Most of the host spaces now provide database management interfaces like phpMyAdmin. After logging in to phpMyAdmin, enter the corresponding database:

And then proceeds to wp_options
the table, then click on Search:

In the search form that appears, we option_name
enter active_plugins
, then click “GO“.

In this way, we found the field that holds the data of the installed plug-in. Click on the edit.

In the form of option_value
a field, its value is modified a:0:{}
, and then click Go:

At this point, all plugins have been disabled. I have to say, method 1 is relatively simple. However, it’s Up to you.
