Error in php after uprading

Hi, I've upgraded to the latest version of php last week. Suddenly parts of code that was working now displays error. The errors I've found until now are related to Sybase (I use MSSQL 2k as DB server) Here is an example: Warning: mssql_num_rows(): supplied argument is not a valid Sybase result resource in /usr/local/www/local-www/ppp.php on line 349 Warning: mssql_free_result(): supplied argument is not a valid Sybase result resource in /usr/local/www/local-www/ppp.php on line 352 I didn't find any changes related to those functions in CHANGES. Any ideas? Thanks! -- *** s2r - public key: (http://leeloo.mine.nu/s2r-gmx.sig)
