After creating a my first subtheme and clicking on settings, I get this error message:

Fatal error: Call to undefined function delta_get_current() in /home/marquitz/public_html/soccermexicana.com/sites/all/themes/omega/alpha/includes/alpha.inc on line 222

I saw on another issue that someone had this error and was able to update Delta and fix the problem. I disabled and then uninstalled Delta UI and Delta API. However, after uninstalling, they continue to show up as present in my module list. I currently have Delta 7.x-2.0 and tried to install another version, but I can't get rid of this one.

Please help. I am thoroughly confused.
