Which browser and version?
Remember that we don’t make the forum software. There is a forum for it which is the best place to ask about compatibility issues:
Make sure you aren’t doing things like disabling javascript as well.
On android. An old opera. Only keep it on my phone because it's the only browser that still blocks all adds, particularly on YouTube.
The other is a current vivaldi my default and fav on PC. But plays YouTube add so I only use it for this forum.
But on mobile neither are showing.
I dont know. I'm rarely poking at my phone. Thou in the past month I can't get to the forum any which way.
Try an up to date browser. I think the days of web developers maintaining compatibility with old browsers died with Internet Explorer, for better or worse.
