I'm not saying it's not impossible to achieve what op want with just style edit (I can probably make it work) but extension is better solution because you won't have to apply the changes every time there is an update and 3.2.6 is just around the corner.EA117 wrote: ↑Sun Apr 28, 2019 7:52 pmI would expect that "Styles Support & Discussion" is the correct place for what's wanted. Maybe I'm wrong, but I don't think "an extension" is what's required in order to achieve what OP wants here. It's the style deciding how to render this information; not something that phpBB itself put together and gave the style "no choice" in changing.
Maybe this is even just a tweak to how the "overlay" is performed, and just make the overlaid custom icon "bigger" and "as large as the icon behind it", even if the icon behind it is technically still there.
But there is clearly something wrong with op installation or something another extension maybe that causes the custom topic icons not to show up at all while the core topic icons are working fine. We don't have that problem so general support seems to be a better choice to ask for help with this issue.
