Trying to fix a plugin

[consolegaming]

Hi, I'm currently trying to figure out how to fix a plugin that we already have installed and which stopped working due to the security fix implemented in version 3.7.

I've learned a lot about the process of vBulletin Products and how they are created. And even managed to find exactly the part I wanted, I just don't know how to implement the fix for the CSRF as it's part of the vBulletin admincp options.

The Product in question is the Split Useronline :

The basic problem is that the saving of the settings no longer work. I presume this is due to the CSRF change. Though from what I've read about it the solution to the problems caused by it is to add the security token on an input element though I've looked at the source for the page and it's already there due to the options being added onto an existing options form. Forums Home Page Options to be precise. So I would have expected it to work.

Or is there something else that needs to be added to the extra form elements to make them work?

I know of how to alter the sections on the page now, though I've gotta say there is no info available on how to get there, documents mention about how to get into debug mode but didn't explain that extra options would appear in it lol. I'll be happy to provide whatever info is required.
