Advanced Search Options not working

[shotgunshane]

Up until a few days ago, the "advanced search option" link inside the "search this thread" option was working in desktop mode on my iPhone 5 and iPad 3. Now that advanced search option link does not work. I can tap it over and over and nothing happens.

I am using the latest iOS on both. Using safari and dolphin browser on both.

Update: the advanced search link works from "search this forum" but NOT "search this thread" on iOS in desktop mode.

Any news on the advanced search link working for search this thread, on mobile OS using desktop mode, like it used to?
