Trouble with Themes Loading
Looks to be installed and I set it to active but the default theme is still "The Boss".... even after removing the default theme.
If so you have to "Activate" the theme once its installed. Go to your dashboard under "Pages & Themes" and click "Activate" next to the them you want to activate. I've attached a screenshot.
The default theme is stored in /concrete/themes/ not /application/themes, so you would have to alter the systems core files to actually remove it. Usually it's best not to mess with stuff in the /concrete/ directory.
change my theme. What I did was delete it, clear cache, re-download or add
to my site, then it worked.
Just let us know if you need anything else!
