Hello All, We have upgraded the Site Builder for Linux from 4.0 to 4.5.0 Hotfix-20090203 (2009020315), and found that a few Image Gallery module upgraded from 4.0 to 4.5, it intermittently shows "Internal Server Error" in the Browser. We try to search it in the apache error log, it shows - However, we sometimes press Ctrl-F5 to refresh it, it can successfully show the Gallery page. But when we simply press F5 again, or goto some pages in gallery and back page, it still shows the "Internal Server Error". Please help. Thank you very much for your kind attention. Regards, George.
