Hi, I don't mean instant page loading, no website really does that. All pages take time to load, even if it's just 1 second.
What I mean is, currently when you select the forum page on your site, it takes you to an initial page that loads quite quickly, then after a few seconds, three circles appear as in a 'loading' type screen. Then a couple of seconds after that, all your forum posts are finally displayed, replacing the initial forum screen.
I'm assuming that this is the reason my forum pages are not cawled or indexed by Google? As when it crawls the main forum page, which it does index, it cannot see any of the posts, because they take a good few seconds to display.
Is anyone else having this problem please? Every single one of my sites pages are indexed in Google, including the initial '/forums' page. But not a single forum post gets indexed in the serps.
