Thanks scacey,

I forgot directory specific.

Just was on the phone with the customer and need to
do some graphical work first.
Later this evening I will have a look.

regards,
Jan

and the link should be in the directory /var/www/htdocs/somewhere/else
create the link by using

Code:

cd /var/www/htdocs/somewhere/else
ln -s ../../some/dir <name of the link>

so that you never have a pathname with "/" as the starting directory.

I'm sorry ehartman, but I have to speak up again.
Either absolute or relative paths will work. I use both. My personal preference is absolute paths because then the location of the linked to directory is clear.

But, ultimately, apache doesn't care. It lives on the filesystem, and (absent the use of VirtualHosts, which changes the "chroot" (DocumentRoot) for different host/domain names) "/" in a URL means "/var/www"

Hi,

I checked with <directoy> in .htaccess that produces a 500 errror
I checked apache2.conf it allows Symlinks for /var/www/*
From the commandline the symlink works as expected.

Seems I must try with something different from CMSMS to see if that is the problem.

[Edit]

I made a simple html-file where I load an image from "/uploads/images/ap/images/image01.jpg"
The directory "/uploads/images/ap/" is a physical directory, the directory "images" inside "ap"
is the symlink.
In Firefox, the image from the symlinked directory is shown normally.

So, it seems a problem in the filemanager in CMS Made Simple.

Regards,
Jan

Perhaps, but I'll say this again (because I spent about a week learning it, back in the day - like to drove me crazy!)
A +FollowSymLinks must be specified for the specific directory in which the link lives.
A +FollowSymLinks for /var/www/ will not turn on FollowSymLinks for /var/www/subdir/.

Hi scacey,

I run kubuntu 16.04 with apache2.
In my apache2.conf it allows Symlinks for /var/www/* with asterix.
I did not specify a directory and still I can present an image out of the symlinked directory.

Do you run another distro?

For the record, just installed the latest CMSMS, 2.2.12 with another wysiwyg editor, that is TinyMCE 3.3
now it is working like it should.

regards,
Jan
