Even if you’re an experienced WordPress user, there are times when a piece of code or the entire plugin will crash your site. More often than not, you won’t be able to detect the problem right away and that’s where debugging games will start.
If you have messed with a code in any core file, you will know what is wrong right after you save changes to those core files. But if it’s a plugin to blame, you might be clueless. And many experts will tell you it’s the easiest way resolve problems is to deactivate all plugins and turn them on one by one until you find the problematic plugin.
You might have more than ten or twenty plugins so deactivating them one by one might be a waste of time. If you’re in even worse situation, you won’t even be able to login to your admin panel to do that after all.
Deactivate all plugins:
- Open you website folder in a FTP client (for example, FileZilla)
- Find “wp-content” folder and open it
- Select “plugins” folder
- Rename the folder to anything you want
Renaming the folder will automatically deactivate all of your installed plugins. If a plugin caused your site to crash and locked you out of admin panel, renaming the plugins folder will allow you to go back into admin area where you can activate plugins one by one. After you activate the faulty one, your site will crash again and that’ where you can start crying or actually remove the plugin which isn’t working for you.
