Why have #Invalid YouTube Link# fields gone invisible on DCF?
I'm not sure when it started, because I don't use YouTube links all that often, but I noticed a while back that YouTube links that I or other people had created in forum posts sometimes seemed to be "invisible" - still there (you could seem them in the BB code when you quoted a post), but they just didn't display. I reckoned that it was one of my Firefox extensions playing up, but didn't investigate.
Today I noticed today that, apparently without exception, all YouTube links are "invisible".
So I tried disabling a few of the likely suspects in the extensions, restarting Firefox each time. No joy.
Then I started up Firefox in Safe Mode, thinking that ought to do it. Nope. No joy.
I don't know if it is relevant, but I have also had a few SMF errors from DCF today, accompanied by the suggestion that the DC server may be busy.
Using IE10, I can see the little YouTube windows OK, but they are slow/laggy to display/render, so I wondered whether their display in Firefox was being delayed/blocked by something.
MY OS is Win-64 Home Premium, and Firefox is v23.0 (via the ß channel).
