I get the same error as well. I log in to Avsim as I normally would, and then I click the Forums button at the top to go to the forums index. From there, I use the search box in the top right corner and I usually search for "roland radar" (no quotes), and it doesn't matter if I hit Enter or click the green button next to the text box, I still get the error message. It has been giving me the same error now for three or four days perhaps. Is there anything more specific you need? I'm also not using TOR, and like I said I am signed in.
