I recently upgraded to the TeX Live 2010 and i see that my documents fails to compile in the case that i have something like
returning ! Undefined control sequence. \@author ->\href
Everything was fine before the upgrade so i am wondering what is going on.
Steps to Reproduce:
1.Upgrade to TeX Live 2010
2.Create that document with \maketitle and autorh with \href
should compile fine as it happened with the 2009 version
Please mark this as invalid as i found what the problem was in the end, after enabling and disabling everything in the preamble.
