"Allocated Memory Exhausted" ? Production server woes!

So I deployed my MODx site to my hosting provider following the instructions in the documentation -- I dumped a backup of my dev server’s SQL db, uploaded everything to the host, restored the SQL dump onto the host, and now.. pain.

When I attempt to log into the manager, rather than the manager window, I get a Javascript error popup containing the HTML code of the 500 Internal Server Error page.

In my server’s error_log, the error is reported as:
[Mon Feb 12 15:25:29 2007] [error] [client <redacted>] Premature end of script headers: login.processor.php, referer: http://<redacted>/manager/index.php
[Mon Feb 12 15:25:29 2007] [error] [client <redacted>] PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 1818107 bytes) in /home/<redacted>/html/manager/includes/document.parser.class.inc.php on line 1287, referer: http://<redacted>/manager/index.php

I’ve not seen this before. Any idea what’s causing it and what I should tell my hosting provider to get it fixed?

Appologies, Ryan.

I have minimal config information about the server from my provider, but I can tell you it’s a CentOS 4 server running php via suphp. Versions are as follows:

apache 2.0.52
MySQL 4.1.20
PHP 4.3.9

Browser is Safari 2.0 on OS 10.4.8. MODx is 0.9.5, only non-standard plugin is PHx, but everything’s working fine on my local MAMP server.

I do not have direct access to php.ini for the host, but the host seems willing to work with me and make config changes when needed.

Okay, so I’m an idiot.

The following thread discusses this problem, which is exactly what’s happening: MySQL 5 on the MAMP end, MySQL 4 on the production end.

I don’t have PHPMyAdmin, though, nor do I have console access. Is there an understandable way to write a PHP script that’ll convert my existing tables to MySQL4, or would I do better to nuke the DB and start from scratch?

You certainly have phpMyAdmin on your MAMP server, and it’s easy enough to install on your remote server; you can even protect its installation directory or simply remove it when you are done.
