I’m sorry but Im new to all of this and I have the same issue.
I upgraded my plugins that we asking for upgrades (Events Manager was NOT one of them). Then i upgraded to newest version of WP.
After this, I got the same error as above.
I FTP’d into my site and changed the plugin folder name to events-manager_foo. Now I can log into my site.
The question is, What do I do next to fix all of this mess?
I didn’t build my site so I’m stuck.
Thanks so much!
