I just set up a Moodle 3.5.12+ on a shared hosting.
On Firefox and IE11 it works but I can't login on Chrome, I get the error "Your session has timed out. Please login again."
I had tried on a private tab and on differents devices with the same problem.
I had a lot of space on disk,
I cleaned the cache,
I deleted the session folder from moodledata and create a new with 777 permissions,
I tried to change the language packet and theme,
I tried with database session and cookies...
Any new suggestion??
