For me, in chrome (it's updated) for the last month or so or more, weird javascript and image hosting related issues have been happening. I turn off all add blocks and turn off all tracking blocker addons I use, for this domain. I believe I've tried in firefox too last month and didn't work.
Here's the issues I've experience or still experience:
#1 Images break and give broken link default icon. not a big deal since I've seen all your avatars by now.
#2 Multiquote button bugs out on me when the images start to bug out on me.
What happens is I click the quote button, and instead of getting the white banner letting me know I qued a multiquote, I get a quick outline of the banner and it goes away. Then when clicking "insert quotes" it doesn't do anything. The way I've been getting around this is just clicking the reply button.
#3 Sometimes the reply field completely disappears for me, eg
#4 And the most annoying one, I'll go to the rock raiders group wall, and type in the box field thingy.. press enter.. and it just makes a new line, it won't actually post my response. Since there's no "post" button, I then just click the like buttons to at least interact to let others know I've read it and support it. eg
Oh, just noticed, see the image issue above? Whenever there's an image issue, other stuff breaks.
Right this moment, everything seems working. Also I don't have malware or any software or connection issues to note. I'm on windows 10 x64 pro newest updates, and specifically using ghostery, AdBlock, and Pop up blocker for chrome, and Quick javascript switcher but I disable them all for this domain. I'm in Nevada USA region, so may be isolated issue with whatever server your CDN decides to use for my region. Would make sense if this is a CDN related issue and a JS file wasn't getting loaded.
Next time it happens I'll inspect/check console to see if there's any error reports that could be helpful. I kept forgetting to do that until after the fact lol.
