On my new homepage I have a problem. I get an error message

Warning

K2 does not have an itemlist table.
Are you using any other 3rd party extensions?

Hi, Krikor! I know that you said k2 does not have an item list table. But It was everything working very well.
After I made update for Joomla 3.4.1 there are this problem in:
prntscr.com/6ljf85
I tried to solve this problem but I couldn't.
Could you help me?
Thanks

You have not answered my question about 3rd party extensions.
You should deactivate them one by one to see which is causing this issue.

It would also help to browse the site with another template to make sure that this is not a template issue.

I'm so sorry for this inconvenience! I will check the 3rd party extensions. Thank you very much.

Let me know about them, also check to see if it is a template issue.

I was looking for an answer to solve this problem then I found this information: Install third party Extensions -
For Free extensions like K2, Acymailing ... they are included in Quickstart package so if you install quickstart package, all the 3rd party extensions are already installed and configure as you see in our Demo.
(www.joomlart.com/documentation/other/install-3rd-extensions)
The problem is: I didn't install quick start package from Gavick template. Now I will do it again so maybe I will lose a lot of time to working in website. This is a very bad situation. I don't know if there are other way to solve k2 error in my website without reinstall template. Thanks

Please read my previous posts.
Switch to another template, or deactivate these extensions one by one.
I never told you to delete your entire site.

Hi,
I switched plugins and modules one by one and I found the problem. It was DPCallendar Attachment. Now my website is working normally. Thank you very much for your attention.

You 're welcome :)
