For the life of me, can somebody PLEASE lend me some help or advice??????????

3 of my plugins: flashplayer, datafdr-ads, mass customs fields manager are giving me this output everytime i want to change some info there…right now i couldn’t change any variables or info there which is really annoying me….Please Pleas help!!

below are the output everytime i try to save new changes:

Nothing found for mydomain.com/wp-admin/tools.php?page=datafeedr-ads
Nothing found for mydomain.com/wp-admin/tools.php?page=mcfm
