Until recently, I had no trouble with my Omeka installation (1.4). When I tried to upload an image, I received the Omeka_Storage_Exception error. When I exchanged messages with my server host support, they replied
"If this required exec() function with PHP then it will not work as we have disabled the exec function."
So, how to proceed? Will upgrading Omeka to 1.5.3 fix this problem, or is this something that I need to negotiate with my server host?
