PHP 4.4.4 to 5.2.6 broke my site!

My web host (Hostgator) upgraded from PHP 4.4.4 to 5.2.6 and from MySQL 4.1.22-standard to MySQL 5.0.51a-community. Now one of my hosted sites is broken. This site has been up and running fine for over a year. It is running an Easy Photo Store script

[B]index.php is giving this error:[/B]

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/photos/public_html/setting.php on line 63
MySQL server has gone away

[/QUOTE]

I did a lot of troubleshooting on a MySQL forum and have discovered that the PHP5 code incompatibility is most likely responsible for this problem.

Here’s the URL: [URL=”http://www.photographybykh.com”]http://www.photographybykh.com[/URL]
However, the Site’s Administration Section is still working fine: [URL=”http://www.photographybykh.com/admin”]http://www.photographybykh.com/admin[/URL]

Going directly to[URL=”http://www.photographybykh.com/setting.php”] http://www.photographybykh.com/setting.php[/URL] seems to result in an endless loop with no errors being displayed.

The access denied for user error has me confounded since everything is correct in database string files and I can log into the admin section of this site with no errors and the site was working fine until the PHP5 upgrade last night.

My customer is upset her site is dead, the developer is unavailable until Monday and Hostgator tech support is not responding to my support tickets–[B]HELP!![/B]
