In testing the CanMys site instance on the new server cluster, a number of problems with the site (not so much the new server) have come up which I have had to address.
First: the privileges on many files were wrong, causing problems with the suPHP on the new server (the php is invoked by clicking on an image, which goes and gets a larger version of the same image using PHP). I fixed the privileges so they were more secure and compatible with PHP.

Second: in the vinland site there are images and a flash player object on a page. When the user clicks on the image, an animation of that image is supposed to appear in the flash player. This works only on IE. The javascript call appears to be ill-formed (according to the Adobe documentation on the loadMovie function).
