As soon as I enable Create Thumbnails, both for Joomla and K2 content, the whole screen goes blank or throws up a 500 error.
Weird thing is, on the home page where I have one NSP GK4 v3.0.0 module enabled, I have thumbnails off, and the thumbnails are displaying (Joomla content).
This issue is in addition to my thread 89-news-show-pro-gk4/86867-arrows-appear-as-grey-boxes.html
