I don’t have anything auto updating. I just updated it through the Installed Plugins section.
It’s all sorted now thanks so won’t bother raising a support ticket unless there’s a log you want me to send in to you?
I also had the same issue when installing the latest Advanced Ads Pro just now. My site then just said “THERE HAS BEEN A CRITICAL ERROR ON YOUR WEBSITE”
To get around it I re-named the plugins folder to pluginsOLD, logged into my dashboard, re-named the folder back to plugins and then re-activated all the plugins… it was a bit worrying for a while there…
