helo, i’ve the same problem. I’ve already test this solution but it doesn’t work for me.
I’m also hosted by siteground and using SG Optimiser to caching my site but i think this is not the problem because i’ve purged my cache and completly disabled the plugin but nothing is changed.
If i click on disconnect a confirm popup appears but when i click YES nothing happens. The popup remain on the screen and i need to click NO button or the X button in upper rirght corner. If i click edit nothing appears, only the “gray screen”.
I’ve already removed and reinstalled the plugin but it doesnt still working
how can i “hard remove” the plugin settings ? it’s not a problem to manage database or code
