Hi
I installed the simple image gallery plugin for joomla 2.5 and php 5.2 it was working fine in previous server. After I moved my site to new server with php5.3 it is giving error "JW_SIG_PRG" at the top of the page. After looking forum I changed ownership and file permission of /cache/jw_simpleImageGallery/ still the problem is same. I even uninstalled and installed plugin but problem remain same. In old server simple image gallery plugin was working well.
Does anybody know solution?

Solution:
The problem was server part problem. It was due to latest GD library which was not compatible with JW Simple image gallery. Please talk with your hosting provider to solve the issue of GD library.
