Hi,
the plugin was only upgraded once to the current version. Original plugin would have been installed February this year.
If you view https://www.jqsbfit2.com on a mobile site and look at the schedule page. The widget shows the gray color that all text had been changed to. I manually edited pages back to yellow but haven’t played with the widgets. The text within the black border was originally yellow.
When I look at the code within the pages the colors are set to yellow….. But appears gray on the mobile site.
Regards
