Thanks for the reply. I pasted the error reporting lines into my main page and into library.php, this is what came up:
Warning: mysql_pconnect(): MySQL server has gone away in /Users/richard/Sites/svn/EmmaStine.com/Connections/connEmmaStine.php on line 10
Fatal error: Maximum execution time of 30 seconds exceeded in /Users/richard/Sites/svn/EmmaStine.com/WA_DataAssist/library.php on line 13
Any idea what would be causing this?
