Hi, I would be glad if you could help solve my problem with k2. After using k2 for two weeks recently I cannot add any more new items, only a blank page is shown. Should I reinstall K2? Please help.

A blank page usually means an error of some type. Go to Global Settings - Server Tab, and set error reporting to highest and see when you try again if an error message is displayed. If so, it will give you a starting point.

Since this worked and then quit working, what changed have you made recently? added components, plugins, or templates? If so, try disabling them and see if that shows you which one is conflicting.

Thanks William White, I set the error reporting to maximum and the blank page shows error cause by one plugin- Metagenerator. I uninstalled the plugin, cleared all cache and now its working fine. Thank you very much.
