I will do a little bit more research, but other than the link you provided I have never seen anything suggesting that the enmity between Wesley and Whitfield was effectively dealt with prior to Whitfield's death. I remember reading somewhere that contemporaries of the period of Whitfield's funeral felt that Wesley was attempting to gloss over his differences at the funeral, and that his comments were seen, at that time, to be somewhat hypocritical.
I would hope that you are correct, but not certain that the link you provided had the correct info. on this topic.
Fair enough.
