I recently moved a website in development from a local install to a web server (liquidweb) and now when I try to save any item, even ones that already existed, it won't save and just shows a blank admin page. Anyone ever experience this and have any solutions?

Probably java script error, k2 dashboard - paramaters - layout tab - set java to load locally
It could also be mb_string is not enabled in your localhost environment
If blank page persists set error reporting high in Joomla global config server tab and see if it throws an error

Thanks for the quick response. It seems that that was the problem and the webhost resolved that by installing the PHP extension. Is there a more comprehensive list of server requirements for K2 for others tat might need to troubleshoot such issues? Keep up the good work with K2. Never do a Joomla install without it...
