s2member is perfectly compatible with WP 4.1.
As your concurrent problem with bbPress sugests, your problem lies elsewhere. You could try looking for a theme or plugin conflict, or for an issue with your host.
I have deactivated/uninstalled/reinstalled the plugins BBpress and S2Member and still see this:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘c_ws_plugin__s2member_pro_rsf_files’ not found in /home2/e559246/public_html/wp-includes/plugin.php on line 496
I changed theme and still see this error.
This only happened after the update to WP4.1 and the plugin itself shows that it has not been tested/
Any ideas welcome!

No, it shows no such thing. It shows that the last report was about 4.0.1. I have s2Member running on several sites on 4.1 without a problem, and the devs are actually currently testing against 4.2 Alpha.
I didn’t suggest that you reinstall bbPress and s2Member. I suggested you test for a theme or plugin conflict. You do that by changing to the default theme and turning off all your other plugins (including bbPress). If the problem disappears, you must have had a conflict.
Then turn things back on one by one and re-test until the problem recurs. Then you will have identified the source of the conflict.
I have a screenshot showing that it is NOT tested with your current version of WP
I followed your directions, and did this systematically and still see the error when S2 is Activated, the error occurs. I obviously am missing something. However, it cannot be coincidental that this site was working fine until the 4.1 update?
Did you activate s2member as the only plugin? What happened then?

That’s not put there by plugin developers (whether s2Member’s or any other plugin’s). It’s a message produced automatically by WordPress when the latest report is not about the latest version of WordPress. So my point stands. It’s just that the last report was about 4.0.1.
Thanks, here is what happens with s2 only activated:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘c_ws_plugin__s2member_pro_rsf_files’ not found in /home2/e559246/public_html/wp-includes/plugin.php on line 496
Fatal error: Call to undefined function mfn_opts_get() in /home2/e559246/public_html/wp-content/themes/bretheon/header.php on line 21
The fatal error is what you need to be focusing on. It’s not coming from s2Member but your theme. That’s where your true problem lies.
You need to talk to the theme developers to get that fixed. When it is, I suspect both s2Member and bbPress will work fine.
I should also point out that you need to bear this in mind when you buy a theme. Plugin devs will not own copies against which to test their plugins, so you are utterly reliant on the theme developer, who can at least obtain free copies of both s2member and bbPress against which to test.
