Still working on it ?
So the line in the .htaccess
is actually to disable the MultiViews from Apache, and as mine is not active, then I think I can comment the line safely.
Then I saw that I had many warning messages because of the deprecated option in the last version of Zend-Stratigility. As I cannot write any command line and I don't know how to edit the composer.json or composer.lock files, then I replaced the directory. No warning messages anymore.
But I think I have an issue with the .htaccess file.
If I try to access to my forum using http://forum.domain.tld, I got a 404 error (on GET / HTTP/1.0)
But when I try to access to my forum using http://forum.domain.tld/index.php, I got a 200 reply. And then it doesn't work because the js and css files are looked for with this path
and that leads to 404 errors on all of them (of course).
See, I am really doing my best ? ... but I still suck ! ?
