No SEO plugin work with wpForo.

See for example:

If you see the html source, that SEO plugin reports wrong title and wrong canonical. Also doesn't seem to "understand" wpForo is active.  I personally do not like all those SEO plugins that put heavy load, like YOAST and the one you use. Use SEO Framework, at least try it. Also activate wpForo SEO. No other option if you want to be ok in the eyes of search engines.
