One day one of my clients contacted me with following error 406 Not Acceptable Error in Joomla while saving article, I tried many searches and found a clue in this forum , Yes the % symbol was problem in my client’s article content, there were in-line CSS width: 100%; line-height: 115%; etc.., then just replaced the % values with equivalent px values, the problem solved and the article saved without error message.
