Thank you for your reply @chike. It's always great to speak with someone to learn something :-)
Anyway, my host provider don't use Cpanel but a "home made" solution. Just to make you know, here is what I have in SSH :
-bash: composer: command not found
and about PHP :
-bash: php: command not found
This shared host have a strict policy for everything. It seem they prefer security and simplicity over functionnality :-)
I was using drush last year, and stopped it because I've read that drush is not the best solution for Drupal. Anyway it was a pain in the *** to use it with this shared host.
I hope one day drupal have an auto-update feature like wordpress, because it's the last point that's missing... But it's another subject.
Thanks for your help, have a nice day !
Sorry to reply to a closed topic but ... I have exactly the same problem.
I don't use Drush or composer. They are not aviaible on my shared host.
I've just downladed an remplaced all files by FTP.
How can I get out of there ?
Thanks,
I've just installed mediteran 8.x-1.29.
I confirm that patch #2 work on brand fresh install of Drupal 10.1.
Someone can insert this patch in next release after 8.x-1.29 ?
I've lost a lot of time because I had a WSOD :(
