Did an uninstall/install... all URLs I've tested seem to work even if I add a ? to some of them.

It seems the reinstall got rid of the redirect to the redirect thing I was seeing... but it just hates this one url. Incidentally this is what its parsing it to... don't know if this is helpful.

redirector.php?url=%68%74%74%70%3a%2f%2f%77%77%77% 2e%69%6e%73%69%67%68%74%73%74% 72%61%69%6e%69%6e%67%2e%63%6f%6d%2f%76%69%65%77%5f %63%6f%75%72%73%65%2e%61%73%70 %3f%63%6f%75%72%73%65%49%44%3d%32%31%26%61%6d%70%3 b%63%61%74%65%67%6f%72%79%49%4 4%3d%34
