Hello reimedia,
Sorry you are experiencing this! I bet this is super frustrating.
We’ll get you up and running quickly.
If it was the activation that was bungled, I’m assuming the files are just fine, just the DB is messed up. But you may need to re-upload your plugins, or just The Events Calendar.
Through Cpanel or FTP, access the /wp-content/ folder on your server. Change the name of the ‘plugins’ directory to something like ‘plugins-old’, this will disable all plugins.
Try to access the admin again, you should be able to get in. Go to the plugins admin page and confirm all the plugins are deactivated. In FTP, change the name of the folder back to ‘plugins’ and reactivate each plugin.
Please make sure you have a recent backup of you site before you start! I’m assuming nothing bad will happen, but better to be safe than sorry.
Does this make sense? Let me know if this doesn’t work for you.
Cheers!
