Answering myself to myself: I cleared the cache and the white screen problem is now solved. At least for the time being.
I have had the same issue now for a week. Firefox gives white screen for my site in Firefox only. Inet Explorer, Safari, work but not Firefox. I haven’t done anything major with the site. There was a plugin which suggested updates and I just clicked on the update, not giving much thought. But I tried disabling all plugins and the problem did not go away. I don’t know how to access my site via ftp to check any of those config files. I did install a client software for ftp access but can’t access anything other than the local PC. I could not figure out how to access the remote site. I did create a ftp user id for myself with a password, downloaded the xml file and imported it into the ftp client but after that I got stuck. Am not a computer person, I just write a blog and this kind of stuff drives me insane.
My firefox version is 60.0.2. Firefox was updated during this week but it was after the problems started.
