Hi,
I am having the same issue as @andcent found here. I’ve tried disabling one plugin and still no success. When I disable the T3 Framework plugin (needed for the newer template) I am getting <blockquote>JError: T3 Plugin is not enabled</blockquote>. And when I disable the JA T3 Framework plugin (needed for the older template) I am getting the following error<blockquote> The plugin JAT3 framework must be installed and enabled.</blockquote>. Similar to @andcent I require multiple templates. Any assistance would be much appreciated.
I’m using Joomla 2.5.9. Templates are JA Mendozite and JA Fixel.
