Hello

I dont know if anyone else has these issues but I am really confused!
I just updated K2 to the last 2.7.0 (I think I had 2.6.7) and all the information images of the products are missing.
In the backend the K2 items now have NO image (there was image before the update in the image tab)!!!

Also I dont know if has anything to do with the update, I installed k2 store and I try to show the price of an item, but the price doesnt appear in the product page. But appears in the category page where K2items are listed.
I noticed that the price loads through this code
?php echo $this->item->event->K2AfterDisplay; ?>
but adding this line to the item.php doesnt solve the problem. I installed k2 store after the update so I dont know if the problem maybe has to do with the new version..?

Anyone can help??

How was this information stored?
Was it K2 Store or K2's extrafields?

It was k2 items that are shown in K2store.
They were uploaded through the tab image in the K2item.
I had made several changes in the K2 template files directly in example in the item.php etc. and I wasnt using overides?
Could this be the reason?

Actually that is the reason. Always use overrides so this won't happen again.

At this point you need to reinstate a backup and move the edits to an override before updating.

This might be also the same reason for not showing the price of K2store in the product page?

I dont remember which files I had edited, almost 2 years ago, so I have to compare I guess...
How do I restore the original archives of K2 v2.6.7?
I downloaded the K2 components 2.6.7 (K2_v2.6.7.zip) If I unzip and upload all folders & files will it be OK?
or I have to re-install it over the old one from Joomla! extension manager?

PS. Unzipping the K2_v2.6.7.zip I see a folder administrator>components>com_joomfish which I havent in my site right now. What do I do?

Since the issue was with editing core files, installing another version of K2 will not solve this issue.
The only way to reinstate these files would be to reinstate an older backup of your site.
