Admin crashed + Highlighter too

Hello!

We have a migrated Joomla 2.5.8 without K2.
We would like to use weather, stock, Image Show, Tabs, highlighter and NSP. Everything was good, but NSP and Highlighter crashed in the admin panel. It said :
error: JDatabaseMySQLi::query: 1146 - Table 'vidget1.jvg25_k2_categories' doesn't exist SQL=SELECT c.name AS name, c.id AS id, c.parent AS parent FROM jvg25_k2_categories AS c WHERE published = 1 AND trash = 0 ORDER BY c.name, c.parent ASC

So we MUST use K2?

Thanks a lot for any help!

Did you changed the source for modules ? When your remove K2 modules are probably still configurated to use K2 so you need to check module and by one and change data source.

Thank! The problem is i can't change the settings, because the admin page of the modul crashed with the error message. I uninstalled and reinstalled it but still don't work the admin page. Have you any idea where can i clear the modul cache after uninstall?

Please try to uninstall module - to remove all files and install again which will load default settings (Joomla! articles as a source).
