w3total cache breaks my dashboard
My wordpress became totally unusable after cache plugin installation. I added W3Total Cache and after applying cache settings, the admin panel turned blank. Now I cannot login and disable the plugin. Any help is appreciated.
Try to disable the plugin using FTP client. What can you do is rename the plugin directoty and then try to access the dashboard again. Flushing the browser cache is also recommended.
I have had similar problem in the past. I had to stop the plugin and reinstall it. To do so I have used wp-cli. Ask your hosting provider if wp-cli is installed on the server and then give a try to wp plugin deactivate w3-total-cache
