Floating Social only works with Yoast WordPress SEO?

Hello –

Through much process of elimination, I determined that the Floating Social plugin will only function properly if I have the Yoast WordPress SEO activated. If I turn off Yoast, or try using the WPMU DEV SEO plugin, the FS code gets inserted into the wrong place in my code (before the head tag, pls see attached).

I had wanted to use WPMU DEV SEO, not Yoast. The FS plugin works if *both* SEO plugins are activated, but as soon as I turn off Yoast, FS code shows up before the head again.

I suppose I could leave both both SEOs activated, but that may be overkill and cause some problems?

Weird… Not sure what to do here.

Any thoughts / suggestions?

Thank you,
