Sometimes just renaming or removing the suspected plugin is enough to shake things loose again. Try using your ftp client to rename or remove just the “app-your-wordpress-uppsite” directory first.

If you find you need to reset the entire plugin folder:

1. Via FTP or your host’s file manager, navigate to the wp-contents folder (directory)
2. Via FTP or your host’s file manager, rename the folder “plugins” to “plugins.hold”
3. Login to your WordPress administration menus (/wp-admin)
4. Via FTP or your host’s file manager, rename “plugins.hold” back to “plugins”
