Some time ago I adjusted the emblem display on the website, but I don't remember which file I modified. I think it was related to the imagecreatefrombmpstring function, but I could be wrong - it wasn't too difficult to fix it. Below I'm sending potential files that may have been changed, compare them with your own files. Also, pay attention to the PHP error logs - often the solution lies there.
