While I installed 1.4-RC2 today, I just figured out something.
If you configure gallery and get this error msg that apache cant read your ..htaccess file and you need to add this:
<Directory /home/usr/public_html/gallery>
AllowOverride Options FileInfo
</Directory>
And I got this error msg in the apache-log:
/home/tore/public_html/gallery/.htaccess: Invalid command 'php_value', perhaps mis-spelled or defined by a module not included in the server configuration
First i thought it was a bad configured apache conf, but I discovered that the problem was that setup/.htaccess was empty, but the apache-conf was file. I got a new setup/.htaccess file and it solved my problem.
Just wanted to let everyone know. Didn't find anything in the faq about this..
PS! I dont really know if this was the real problem, but when I looked trough my ssh-window it seemed that did the trick. KEEP THIS IN MIND!
