I'm having an issue getting a custom module's menu item to show. Normally it is set to appear to the right of the System menu item in the dashboard however it is acting abnormally.
I do a clean install of CE 184.108.40.206, then install the custom module and it works perfectly. Shows as intended.
I attempt to install this custom module onto the client's production 220.127.116.11 website and it refuses to show. I've verified that it is registered and enabled under
System > Configuration > Advanced > Advanced. I've tried clearing every type of cache both manually and through the admin panel, I've reindexed, logged out and back in dozens of times, checked error and system logs along the way and still nothing.
My assumption is that something else on the client's site has a duplicate naming convention or similar that is overwriting my custom's modules menu item presence as it works perfectly on other sites of same version.
How would I proceed with debugging? Should I be putting logging commands somewhere in my modules controllers? Is there a better way?
Thanks in advance.
