“This one is not easy to reproduce and we looking the solution to fix it.”
You could either log in to my site or I could give you a backup version that you can install with duplicator. I just need this fixed fast.
“You mentioned that the plugin was re-installed, did you manage to connect the same FB page as before? Do you see the same error when connecting FB page?”
It was already connected when I installed it, it does not let me disconnect.
When I put log out of facebook the log in button appears, when I click it it automatically connects and it does not let me disconnect the page, the error I mentioned appears.
