I am still having this issue and I have done many many things to try to fix it. I amn locked out of my site, but thankfully to the user it still looks like the site is fully functional, which the user end is, just nothing of my admin.
-I’ve tried fixing it with the things suggested in this thread.
-I’ve tried rolling back to my previous installation, this will not work.
-I’ve turning off all plugins
Please I can not update my site and its hurting my traffic immensely!!
