After moving site to a new host, and updating the config file - the site was bringing up a blank white screen.
I went through and installed a fresh install of the base Oxwall and installed all the plugins I purchased one by one.
When I installed the Theme Changer, the site went to white screen.
I deleted the plugin from the site and the site works.
I went back to my "moved site" and removed the plugin from the site and the site is now functional.
Installed it again and immediately got the blank white screen?
Any suggestions - is there a setting "required" for the Theme Changer that the Oxwall doesn't use?
