I cannot open the Cerulean, Diametric or Quantive templates with Firefox 10.0.3 or IE 8.0.6x. The server spins for a long time and eventually displays a white page. There are no errors in the log or the browser error console. I can, however, open Crystalline and all the default Joomla 2.5 templates. The website itself displays correctly. I am on an intranet in a large enterprise where I do not control the browser versions. Is there a workaround?
