I tried it again in Firefox and I got the same issue. I tried disabling all of my addons on chrome(which is my main browser) and while it was working temporarily for a few seconds I still kept getting the error message. Disabling my anti virus programs did not work either. Clearing the Cache also didn't help the issue. So here is the issue in a bit more detail. I am trying to make a new thread of private messages to a friend of mine. When I press the "new private message button" and I begin to type in the recipients name or any name for that matter in the recipient box it will begin to search for the person to send to. At that point I get this error: <a href="http://gyazo.com/ec8381e2ead37bbdede5772084ebee23" rel="nofollow">http://gyazo.com/ec8381e2ead37bbdede5772084ebee23</a> this happens regardless of which browser I am using, whether I have any addons disabled or enabled, and whether or not I have any anti viruses on or off. Here was what I was doing step by step. 1. I went to my account name at the top right of the screen and left clicked on it and on the drop down menu I clicked private messages. 2. Once on that page I clicked the blue "New Private Message" button 3. Once the GUI popped up to send my message I typed in the recipient's name and was waiting for the drop down menu to choose his show his name in the dropdown so I could click on it 4. Once it begins to search, this happens: <a href="http://gyazo.com/ba0d9a3a03203ac9116d065f8f7861a6" rel="nofollow">http://gyazo.com/ba0d9a3a03203ac9116d065f8f7861a6</a> Here is the console log from when the error pops up with no addons in the background: <a href="http://i.gyazo.com/f808ad4532eec31b1dfb29f6348301af.png" rel="nofollow">http://i.gyazo.com/f808ad4532eec31b1dfb29f6348301af.png</a> I am using Google Chrome with these addons enabled(I also tried with these disabled but I continued to get the error.): Google Docs, Google Sheets, Google Slides, Hangouts, Kaspersky Protection, Magic Actions for Youtube, reddit companion, Terms of Service: Didn't Read, Twitch Now. I have Windows 8.1 as my OS and I use Kaspersky Internet Security, aswell as Malwarebytes Anti-Malware. However I disabled those two anti viruses and tried to send a private message and I still have the issue.
