I'm trying to swap from an old version of Realex payments module developed by SF9 to a new one built by Yoma. Both of these modules use the same resource name and the same table names so to get the new plugin to install I've removed the resource from core_resources and dropped the tables.
I've managed to do some test payments successfully however there seems to be one small issue with the module, the payment option displays twice in the checkout. this seems limited to just this modules payment options as the default magento options I've tested only display once.
The html output for these is also identical so it seems like a accidental dump of the same item twice. so while i could hide one with JS or CSS I'm trying to avoid this option for now.
Unfortunately there is seems to be no support for this module from what I can find, so I'm left trying to debug it by myself.
I've gone through the code and tried to debug the issue myself however I'm working blind when it comes to adding a new payment option. What would be a good string to search for, or a config option I need to look for that would be prudent to look for to find a duplicated payment option?
I have now installed a fresh Magento installation and just the module with the same settings and it doesn't display twice.
So I turned off every non standard Magento module and set the theme to default on my staging site, but my staging site is still showing the payment option twice. So i assume this must be something to do with the database.
