If there's something that everybody hates about Magento it's endlessly configuring your modules before being able to write some code. I'm trying to collect a list of common Magento configuration errors for a future project that's I'm close to launching.
I'm looking for specific examples of things like using the wrong naming convention on classnames, forgetting the <class /> wrapper when setting up grouped class names. Little things like that that drive you batty for hours until you realize your error.
The more details the better!
in /app/etc/module/your_Module.xml camelcase codePool otherwise will fail
<?xml version="1.0"?>
<config>
<modules>
<Your_Module>
<!-- <codepool>local</codepool> this will fail silently-->
<codePool>local</codePool>
<active>true</active>
</Omx_Hooks>
</modules>
</config>
