Took me a while to get this figured out but found problems with this plugin using different browsers in my Macbook-Pro in the settings section.
Using Chrome:
… On General tab: The Save Settings button works for changes on that tab as expected.
All the other tabs: (Overall Rating,Rating Styles, Create Ratings) The Update buttons do nothing after making changes. Does not do any type of post at all. No changes are saved.
Using Safari:
Everything works for updating on all tabs. However, the Overall Rating tab (“Overall rating color code”) AND the Rating Styles tab (“Rating Color”) which shows as a color picker dialog in Chrome is not there anymore and is replaced with a text edit field that shows the code. i.e. #ff9900.
I am having to use Safari to make any changes to the settings but would rather use Chrome once this gets fixed. 🙂
Thanks!
