It took me a while to trace down this bug, it’s a little hard to repro but:
Requirement: there are ads displayed on Topic list top ads
, in my case simple HTML text ads.
Issue: category browsing (at least from the sidebar) breaks after a few clicks. All Categories shows a random category, and visiting category A might show the same topic list
Repro:
- Click category A
- Click category B
- Click “All Categories”
- Click category C, C has subcategories, set to “none” instead of “all” subcategories
- Click “All Categories”
- Repeat
- Issue described above should appear by now, otherwise repeat.
Repro is basically some random browsing between “categories” and “all categories” and other sequences might give the same issue as result. 2-3 rotations should definitely result in repro.
When the Topic list top ads
ads are disabled, zapping between categories and “categories” and “all categories” works as expected.
