One of three toilets flushed fine except when there is any toilet paper involved and then... plunger man to the rescue!
Experienced advisors suggested wax ring is mispositioned or calcium build up or burr on an unglazed portion of path in trap section of toilet construction OR something fell in and is causing blockage.
The recommended tool is a CLOSET AUGER . . . NOT a regular plumbers snake! There is also a closet auger mat to place in the bowl to protect against unsightly mariing of the finish. I was advised to get a good one so went to Lowe's and dropped $22 for auger (cheapie for $7 didn't look none too sturdy) plus a $7 mat. Save your money on the mat and cut one out of a gallon milk bottle.
Don't know what it removed but it fixed the problem in a couple minutes of labor.
