I have a successful, working install of 8.6.4 and am following the “manual upgrade” notes. It says to put the site into “Maintenance Mode” but when I do I get an error that “The website encountered an unexpected error. Please try again later.”
Anyone know what is going on? I’m wondering if it’s somehow a permissions thing and I need to make myself a higher prived admin…but haven’t a clue why I’m not already as high as it goes.
Took a close look at other posts and it seems like everyone else’s issues are afterwards. In my case, something’s preventing the maintenance mode from even showing up. Is it that I need to install a module for this? It’s not in core?
Scratching my head. Thanks in advance for the help!
