I've installed Wordpress & Semiologic free several times without any problems. However, on this occasion I have installed Wordpress into a subfolder: http//www.sitename.com/subfoldername/
When I upoad the Semiologic files and then try to select the theme my browser (Firefox) hangs.
- I have downloaded and reuploaded the Semiologic files to my server. - I have checked folder permissions.
Installed properly, Semiologic works equally well whether in the root directory of a domain, in a subdomain, or in a subfolder as you have done.
The key word is properly.
If your host has Fantastico in its cPanel, use that to install WordPress and then upload the free Semiologic theme into the theme folder. Be sure that the versions of WordPress and Semiologic are compatable. WP 2.51. Sem 5.5-rc3.
I think that the problem is a version incompatability. If you are installing wordPress using Fantastico, the WordPress version is probably 2.5 or 2.5.1. Check this.
The version of Semiologic should be 5.5 something. I don't know whether this has been released in the free version or not. But if you are using the 5.0 version, it will not work with WordPress 2.5
If you have used these same versions on a domain and everything works, but doesn't work in a subfolder, it would be due to operator error. Recheck your installation? Semiologic downloaded into the theme folder?
