Before that, I had these plus the formatting toolbar and it did not work. Removing the formatting toolbar fixed it. That’s all I can say. If it can’t be reproduced, could it be the interaction of two or more plugins that caused the problems? Or the problem was solved by something else (though I wouldn’t know what) that coincided with the removal of the plugin?
