What I’m seeing is:
This error occured after updating a wordpress plugin that gave an error saying basically the same as on the screenshot above, then a page with something like “maintenance try again later” something like that. After refresh the error of the screenshot occured.
I am using the softaculous plugin & a domain from godaddy+cloudflare dns. I have setup the mx records the website worked also, but cannot enter the roundcube mail.
I don’t know what to do now. Hope you can help me out guys, i have put lot of time in the website!
