@alexander : Yes, I updated my other sites, and they work fine.
The site I have issues with just became a white screen.
I still can access the dashboard.
First I thought it came from a plugin, so I disabled them all, then when I checked if the website worked with disabled plugins, it worked, but it had reverted to the default theme.
I clicked on “themes” and Hueman was deactivated. When I tried to reactivate it, there was an error message saying that theme wasn’t installed or something like that.
I’m gonna try reinstalling it now and see what happens.
On a side note, would it be possible to have a changelog here one day, when I update, I never know what changes are happening. I know there is one on your website, but it doesn’t match the version of the theme that’s here on wordpress.
