I'm a newbie to site design, and recently stood up an internal Development site.
I've been working on this for a few weeks, and I was in the process of updating a global stack.
when the site became non- responsive.
After doing a page refresh
I get the following error:
An unexpected error occurred.
Call to undefined method Concrete\Package\ThemePalette\Theme\Palette\PageTheme::getoptions()

I can get to the Dashboard of the site, but whenever I try to load a page, I keep getting the same error.
I'm not quite sure what to do, or where to look to fix the problem.
I don't have any backups, so I'm looking to lose 2 weeks worth of work.
Any assistance would be appreciated.
If this is the wrong forum, could someone point me in the right direction?
