First things first, I disabled my ad blocker for this entire site, and I have tried with WYSIWYG editor and with the code visible. None of that has any effect.
I can reply to certain posts with quote, and others, nothing appears at all when I try that option. I type up messages with posts quoted that I have replied to, and I preview the message (have to, because of the board’s incredibly tiny edit window) and the entire message, the quotes, the text I typed, it all vanishes.
It makes it particularly difficult to respond to certain threads. Lots of my work vanishes or replying to people is impossible. Additionally, some posts with a quote are preview-able and then post-able, but once I do, if I try to edit the post within the window, the text all vanishes. Quotes and body.
The problem is intermittent but significant and persistent. It happens in most of the threads I’m active in, and most of the posts I try to respond to. It doesn’t happen all the time. Quotes seem to trigger it, but not always. I’m not touching the quotes most of the time. Just throwing quote tags around text I type myself causes the same issue, I believe it is the cause anyway. But because the problem is intermittent and doesn’t happen under the same sets of circumstances all the time, I can’t rule out the idea that it isn’t actually the quotes causing this.
Running Windows 8.1, Firefox as the browser.
Doesn’t happen on any other vBulletin board I frequent, just here.
