Due to a PHP upgrade on my server, one of my installed plugins stopped working and throws a fatal error. As I can't login to admin area of the site as a result of the plugin failure I can't uninstall that plugin. Now can I delete plugin's files directly using FTP? Will this cause any problems?
I've found, the culprit plugin was unnecessary, I've removed the plugin files using ftp, now site is back, no errors. But I dontt know if this is the proper way. If that plugin were necessary, I would reply the files using new available version.
