hi all
I changed hosting to my site.
now when I save an article I get a blank page.
I turned on error reporting and now I can read this
Fatal error: Call to undefined method JApplicationAdministrator::getLanguageFilter() in /web/htdocs/SITE NAME/home/modules/mod_k2_content/helper.php on line 184

Anyone has any idea about that?

thank you
Elena

Please try reinstalling the latest version of K2.
DO NOT uninstall, simply install it on top.

Hi Krikor,
thank you for your reply.
I tried, but it didn't worked.
any other idea?
Elena

@elena ecaterina casartelli

The error indicates that somehow the K2 content module is triggered in the administration area.... This means that probably a plugin which is triggered on item save is executing the module code.

Try the following:

1. Disable all third-party K2 and content plugins.
2. Ensure that you are using the latest version of Joomla!.
3. Ensure that you are using the latest version of K2.

Thank you.
I toggled all k2 extra components and now it works (slow but it works)
now I try to activate one to one and understand which one is the problem-generator.
I will post it later, so maybe it can help someone else

Did you find which extension was causing the issue?
