Hi,
Since the latest forum upgrade every day the first time I access the forums (via a bookmark) it displays the loading screen then hangs there indefinitely. A reload will load the page normally. Not sure if there’s anything to do/can be done, just mentioning.
Chrome 107, w10.
Try to clear the cache in the browser 
Did not actually. Also load time for the first time takes forever but this is not specific to rum-x; also happens on other sites recently that use the same forum engine. “Upgrades” I guess…
It’s not a big issue to hit F5 once a day. 
It’s a combination of both.
I’ll keep an eye on the updates. I’m sure a solution will be provided there soon.
So there’s some request that takes 19-22 seconds to serve (it grabs a bunch of scripts and stylesheets) then for initial loads or if I disable cache will not clear the loading overlay. There’s also no no content inserted on the page either at that point, it’s practically a blank document. Hitting F5 will download/render the normal page in less than 2 seconds total.
Doesn’t seem to be happening anymore, at least it didn’t in the past 1.5 days.
Then my optimization helped. Great. 
Thanks for your feedback.
