Hello everyone!

I've created my k2 categories and items on joomla 3.0

But then I decided to use joomla 2.5 because some of extension feature doesn't support joomla 3.0
Then I just installed joomla 2.5 and imported only k2 tables from my joomla 3.0. It was great before I logged out. But then I can't enter to my admin panel that "Username and password do not match or you do not have an account yet." error report. I've changed user Id section from users table. reset password from phpmyadmin. But useless. What should I do, what should I consider to import k2 table to another web? Does it depends on joomla versions?

your user probably doesn't have the right access level anymore, try this:

within phpmyadmin, go to the table "xxxxx_usergroups" and look to see what "id", is "super user" (mine is 8 )

go to the table "xxxxxx_user_usergroup_map", find the row with the same "user_id" as the user within "xxxxx_users" that you want to give admin access to, and changes it's "group_id", to match the one within "xxxxx_usergroups"

That's working, thank you very much, you saved my life!

glad to know it worked :)
