first, I hope this is the right section
Then, when I try to send a private message to someone (I tried to send to some random guys) I got this error: "The string you entered for the image verification did not match what was displayed.". I think it refers to the 'Human Verification' section on Private Message. The problem is that I see a blank/white space on that section, there is no image verification that I can see. The error started to come out 1-2 weeks ago, and every day I have this error, so I suppose it's not a clearing chache problem. I have re-installed my OS in November. Do you have any suggestion about? Or if others had had this kind of problems and found the solution , could you please help me?
