Bugs in the new site interface

Just started using your new interface and immediately ran into glitches.

 In some threads with my maps, the preview images disappeared. Well, I figured no big deal, I'll fix it right away. I clicked "edit," inserted the images, and clicked "save." The images started displaying. But after that, in all my map threads that I edited, the thread titles stopped displaying. All these maps started showing without titles. I try to insert the title, click "save," and it just won't save.

Also, my signature isn't displaying, and in the new interface I couldn't find the button for editing the signature at all. Does it even exist?
