This is strange: SFC stopped working all of a sudden. I found that the TOKENS were not enabled. Also found that the BLUE button to enable the TOKENS was not visible. Went through several steps to locate the problem; disable other plug-ins, checked my settings on Facebook Developers. Note, all of this was on my NEWER Windows 7 computer. Was just about ready to do a reinstall but decided to look at the setup on my OLDER XP computer. When I did the BLUE button was there and I was able to re-establish the tokens.
Went back to my Windows 7 system and found the BLUE “GRANT SFC PERMISSIONS” button was now visible there too. Now waiting to see if SFC works correctly when I do my next post. WEIRD
