Plug in failure in Safari

Hello,

I was wondering if someone may be getting a plug in failure using Safari using OS X El Capitan,  I try removing and re installing flash player but still having the same issue.  One thing suggested was to try to get an earlier version but I can't find any. All links are pointing to the newest release.  Any suggestions

here is what I've done so far

Uninstall flash using the app

removing the 2 folders from library

re installing - no success

Install silver light.  It made it worst.  OS X froze up  I had to do a hard reboot to get back in

USING OS X El Capitan

verions 10.11.6

16 MB RAM

500 SSD drive

Basically when accessing a site. it attempts to load. and then it comes back with message plug in failed.  Any suggestions.  or at least can someone point me to an earlier version of flash before the last release?  Otherwise, the only option is to re install OS X

Thank you
