V7.5.8 and onward have their own implementation of shareaholic, which ex expanded upon in the UBBDev pages, it'll be changed in v7.6.0 to reflect the UBBDev pages.
Basically all that is needed in the UBB is the shareaholic key and setup code, then it places it's own snippet on the thread view pages; then it can be expanded with the notations on the UBBDev page.
You're more than welcome to add code manually, it'll work either way, but we cannot provide support on modifications to code on this support forum (as the 3rd party support here is generally for stock forums, whereas UBBDev is the 3rd party site for modifications and development)
