I once had a similar problem after moving from one server to another..
the problem was the ownership of the files..
they were owned by the script that moved them.. a real pain..
they could not be executed by anyone except the script that moved them..
this does NOT happen if you upload with a normal ftp program.
But if you overwrite the files with the ftp program, they still keep the first ownership..
Solution: reinstall in a new directory uploading the files with ftp
-------- just checked your server again
.. seems it doesnt like the permissions of you main gallery directory,
error: Directory "/srv/www/stallboard.de/public_html/gallery" is writeable by group
that meens you have the main directory of gallery
with permissions like 771 or 777..
Your server doesnt like that.. try 751 (thats my setup)
compare permissions of forum directory and gallery directory
other possibility, if you used a "normal" ftp program.. the program did not switch automatically from binary to text mode when uploading the php files..
What I would do..for testing..
make a file test.php with content <?php echo 'test'; ?>
upload it to that directory and see if it works..
if yes.. copy all the gallery files to that directory the same way you copied the test.php
just set directory: files and users to 777
leave the others alone... (they should be: 755 (strange enough just checked my server, they are 751 and it also works..)
as for the php files on my server they run with 750 ...
644 should also work.. but somehow they are now 750... (strange)
do some tests with test.php file.. maybe your server is setup so that php files work only with other permissions...
compare with running php files in other directories.. like forum also compare ownership
thats my 2 cents
