Hi,

There was problem in my Joomla 2.5 so I uninstalled it and installed 3.1 version. I was using K2. Now I have installed the K2 again. All the items are visible in the new version. But my old website links are not working. Example here!
In control panel, when I click an item, it says: JUser: :_load: Unable to load user with ID: 379

What I tried:
1. deleted the users_groups and users tables from the database.
2. created new tables from the backup file of K2.
3. inserted the old users and user_groups

but it is giving the same problem even there is a user with userid 379.
What do I need to make the old items to work again?

Hello Muzamil,

There are more dependancies than the users and it is a bit more complicated. What I suggest is either manually change the author to one that already exists in your Joomla!(not K2) user groups, or reinstate the old Joomla! 2.5.11 website and use an extension like Admin Tools to upgrade to 3.1.1

PS. backup before doing anything
