Thanks, it’s the both pricing packages and the tables further down.
I’ve found a quick fix (giving those colours values didn’t work):
I saved the comparison tables as a module, removed them from the affected pages, ran the ccss, then added them back after the ccss generated. The errors aren’t resolved, but because there were less errors, the ccss generated without issue.
I will need to get in touch with Power Pack and Ultimate Beaver about these errors.
Thanks again for all your help, it is most appreciated, and I can finally rest easy now that I have ccss for all my pages.
