500 Internal Server Error

[hameau]

... but always got the 500 Internal Server error:

Almost certainly a file permissions problem. Check again that directories and files have permission set to 0755.

I guess you are with Aruba for your hosting? See their help pages about file permissions and how to correct permissions. (Links to their English pages, which I found easily with Google.)

Make sure that you have not changed this part of the gsconfig.php file:

Code:

# Set override CHMOD mode
#define('GSCHMOD', 0755);

I apologise in advance if you have already followed these suggestions! Please confirm that you are actually hosted with Aruba.

Edit to add: I see that you have Apache v2.4 – may be significant? I have no experience with this version.
