I am developing a module for Magento that calls a web service and adds a cookie. I want a method in a class to be called when a user is saved ( customer_save_after ). I was somehow able to get it to work when developing on localhost, but I get this error on the live sites where I've attempted to implement it:
Mage registry key "_singleton/Eight18_Aqui4_Model_Observer" already exists
There is a similar thread here, but it leaves out the actual detail on how the problem was fixed.
Here is my config.xml: (the customer_save_after event seems to be where the error starts)

And finally the system.log file:

Short Version: Your production system is running in "compiler mode" and you haven't compiled your module classes.
Your production server is running with Magento's "compiler mode" (self-link) turned on. You can tell by the error message Magento's logging
ERR (3): Warning: include(): Failed opening '/var/www/clients/client3/web4/web/includes/src/Eight18_Aqui4_Model_Observer.php'
for inclusion (include_path='/var/www/clients/client3/web4/web/includes/src:.:/usr/share/php:/usr/share/pear') in /var/www/clients/client3/web4/web/includes/src/Varien_Autoload.php on line 93
Magento's looking in includes/src for a class. That's where compiled classes are placed. Also, PHP is trying to include a fully underscored file name Eight18_Aqui4_Model_Observer.php. That only happens when compiler mode is on.
When you push module changes to production you need to recompile your modules. You can do this from
System -> Tools -> Compilation
or with the command line compiler script
$ php shell/compiler.php
Usage: php -f compiler.php -- [options]
state Show Compilation State
compile Run Compilation Process
clear Disable Compiler include path and Remove compiled files
enable Enable Compiler include path
disable Disable Compiler include path
