Hi Bruno (and thanks a lot for your commitment)
I’ve tried to switch .htaccess file to 664… with no success unfortunately. So I set it back to 644
As for the permission of posts, it’s 644
All your permissions are good, not a group issue. I don’t catch what’s going wrong. Sorry.
Hi, a thought in the end of this beautiful afternoon, did you change the theme of your blog before encountering the issue ?
