Hello,

In my opinion it is not an issue in our template, becuase the error comes from the core joomla code.

Hi Dziudek,
Thanks for your response.
hmm what you said may be correct but while i am installing "meet-gavern" only i am getting this error right.
So the possibilities are,
Either "meet-gavern" not compatible with or having some function issues with joomla.
Else "Joomla" having some issue to invoke its (Meet-Gavern) functions.

I just to know which side the problem is?

Please try to install this template on other joomla installation - in general it is a first time when we got this kind of report, so probably it is an issue with your Joomla instance.

[nagedoer]

Yes i will do and keep you update.

Hi there,
As you mentioned i have installed the joomla 2.5.14 then while installing gk_meet_gavern_quickstart_J!3.zip got the below mentioned errors.

[dziudek]

Why you have installed on Joomla! 2.5 the template for Joomla! 3.x only? It cannot work.

[nagedoer]

Yep, i forgot to saw that.
Thanks for your time.

[nagedoer]

But the installed joomla was affected how can i get back the same?

[dziudek]

The only way is recover a website from backup.
