I have been able to see it for weeks. There must be an issue with the cache on your computer, kitare. Try refreshing the page and if that doesnt work, the only other thing I can think of is holding shift key while you refresh.
The two styles have separate folders from which the logo to be placed at the top of a page is selected. The folder for prosilver contains the logo but the folder for subsilver 2 does not, hence it does not display.
When I created the logo last year I think someone sent me a PM how to get it into the folders concerned but that message has long gone and I can not rememebr how to get it into the folder for subsilver 2 or even what the name of the folder is. So any help in that area would be appreciated.
