I started my wordpress website by using an old domain name that I have through WebsiteSource.com and I didn't have the choice to choose my theme.
Therefore, I went to the theme page and tried to download one (Dynamic News). Then, Wordpress tells me that the theme has been installed successfully but when I click on activate, I've got a "Server Error 500" message on my screen and each time I click on the left hand side menu, I've got the same Error message.
Is anyone knows how to fix that?
PS: I also tried to download directly the theme separately and then to upload it but I still have the same problem.
