Apologies for the triple post, but it’s been too long since I posted the last one to edit.
The remote DB is now in sync with the local DB relating to the Newsletter fields. But now it’s not allowing me to create new newsletters on the remote server (works fine on the local one). Clicking on “New Newsletter” results in “You do not have sufficient permissions to access this page.” even though I’m logged in as the admin user.
I’ve tried deleting the plugin and reinstalling, and disabling all other plugins, but nothing has worked. The rest of the plugin seems to work fine, just not the New Newsletter.
Any help would be greatly appreciated.
