If you don't have access to the WordPress administrator page and wish to disable plugins, there are a couple of easy options for you.
How to disable plugins via WordPress Dashboard
If you have the WordPress dashboard integrated into your panel, you can click on Plugins & Security:
There, you will be able to see all the plugins that are installed on your website and disable them one by one:
How to disable plugins via File Manager?
If you don't see a WordPress dashboard or prefer managing data via files, you can disable plugins using File Manager.
Step 1 - Open File Manager
Open the File Manager of your website and enter its wp-content folder (domains/yourdomain.tld/public_html/wp-content). There you’ll find plugins folder:
Step 2 - Check your plugins and disable them
If your website doesn’t use Elementor, to disable your plugins just rename the entire plugins folder to plugins_disabled (or any different name) - this will make all the plugins inside this folder disabled:
If your website is built with Elementor, then rename every folder except Elementor. You can also create a new folder and move all folders inside the plugins' directory except Elementor. Elementor has a special structure, and changing the plugin’s folder name can cause a site crash. Please make sure to not change the Elementor folder name.
Both options will disable plugins, as the path to files will not be correct anymore. Renaming the folders or moving them back to the /plugins directory will enable the plugins again.
If you disabled plugins to find out which of them interferes with the website, and after disabling plugins the site is back online, then your next step would be checking plugins one by one:
Disable all the plugins:
If you did changes via WordPress Dashboard, simply make sure that all the plugins in the list are turned off
If you used the files method, rename the folder back to plugins or move all files back to the plugins' folder. After that, rename each plugin's folder to disable them separately
Start enabling plugins one by one, checking the website’s availability in the incognito mode after each plugin
No matter which method you choose, you will be able to find the corrupted plugin, so your website would be running without any issues! 😊
