Magic Quotes

[webhost]

We have always had magic quotes in ther php.ini set has so.

; Magic quotes
magic_quotes_gpc = off ; magic quotes for incoming GET/POST/Cookie data
magic_quotes_runtime= off ; magic quotes for runtime-generated data, e.g. data from SQL, from exec(), etc.
magic_quotes_sybase = off ; Use Sybase-style magic quotes (escape ' with '' instead of \')

Tonight a client ask they be turned on like so

; Magic quotes
magic_quotes_gpc = on ; magic quotes for incoming GET/POST/Cookie data
magic_quotes_runtime= on ; magic quotes for runtime-generated data, e.g. data from SQL, from exec(), etc.
magic_quotes_sybase = on ; Use Sybase-style magic quotes (escape ' with '' instead of \')

After we turned them on we got database errors like so.

Parse error: parse error, unexpected T_STRING in /home/user/public_html/forums/global.php(305) : eval()'d code on line 1

What is causing this? How can we leave the magic quotes turned on and not have all those errors? Does it to all vbulletin boards.
