This morning i updated 2.6.6 tot 2.6.7. Now i get the following error.

'Invalid backend configuration.
Readable volumes not available.'

I have read the topic:
getk2.org/community/New-to-K2-Ask-here-f...2&start=36#13872

But i only have a few extensions and i disabled them all one by one. I have also set "error reporting" tot none but that doesn't help anymore. In 2.6.6 it helped.

Can you help me?

Kind regards
Ronald

I found the problem, two of the files in de directory /public_html/administrator/components/com_k2/lib/elfinder contain a "Create symlink" and the scanners of my webhosting see this code often used by hackers and therefore they were removed.
The webhosting company says that it is not common to use "symlink" on a webhosting server.

What is your opinion concerning this issue?

Hello Ronald,

Some users use the symlink functionality that elFinder has. If you have a site filled with images and content it is not uncommon to use a symlink to point to folders with images for better content management.

Hi guys,

Installed a fresh Joomla 2.5.17 with the K2 2.6.7
Same error message here, after setting Error Reporting : None.
Installed a fresh Joomla 2.5.17 with older K2 versions 2.6.6 and later on the 2.6.5

Same errors....:
'Invalid backend configuration.
Readable volumes not available.'

The files with the symlink codes in them are there, so I suppose they are not causing this problem.

Kind regards,
Edze

Hello Edze,

Is your hosting provider supporting symlinks? The files might be there but the host might be blocking these requests.

Hi Krikor,

Thank you for your fast answer!
I will write an e-mail to the hoster and ask them.

Kind regards,
Edze

Hi,

Hoster is not supporting symlink for security reasons.
I wonder why K2 needs symlink in their Media Manager whilst the standard Joomla Media Manager is working fine as it is?

Anyway, things being like they are, I might have to look for another CCK, just as sophisticated as K2....

Kind regards,
Edze

Symlinks are not required by default. The media manager works with the standard /images folder.

Symlinks are used in cases that
a) You want a different root folder outside public_html
b) Want to store your data across multiple folders

If none of these applies make sure this folder is not full and do not forget to ask your hosting provider about any limitations regarding your hosting plans.
