Note that I updated the component on the test site deployed 2 days ago, and I had the same error. I re-deployed the site a few minutes ago and reinstalled the theme component, but the advanced search still doesn’t work when the component is active, and the error is still visible.
That suggests your javascript is breaking somewhere.
it’s not failing on Starzen, which I’ve just rebuilt, so I can only assume it’s some javascript from some other component you’ve got which is interfering with it?
Do you use Layouts? I’ve also deployed the import update to that this evening.
You have no other suspicious output on console?
Have you made any other changes, introductions of new components?
Sorry, I should have checked other components. It’s caused by a conflict with Topic List Author which I’ve removed from themes using TLP, no problem. FYI @Lilly
Hah I was just testing this and was about to post here that the two components are not compatible at the moment because both override the topic-list-item template.
