I did not reinstall K2. If I just reinstall it, will I lose my content? Is there special way I have to do that?

You shouldnt loose your date, BUT, always back up first!

I had read one of your posts on here somewhere that said you should uninstall any k2 extensions first? Is there anything I need to do or just reinstall over the old installation? (Backed up with Akeeba already, thanks!)

Thanks for your guidance.

Sorry for the delayed post, i try 3 different browsers (IE8,Firefox,Opera) and all ruturn no errors. I ask our provider for support they update their php version and the information page work fine, but the problem with the item image upload page stay, now just don't return blank page - just don't upload image. The intersting is that the image upload for categories work fine jut for the items don't work. I check the directory permissions and tree but they are ok.
Thanks for your guidance.
With regards,
G.M.

hello.

Check this solution :

in the file: administrator/components/com_k2/lib/class.upload.php search :

               $this->mime_file                = true;     // MIME detection with UNIX file() command

and change to

               $this->mime_file                = false;     // MIME detection with UNIX file() command

Thank you for your answer, problem been simple -> folder permissions to item image directory.

Did this solution work for you?
I modified the files also but still blank screen
