I have been working on this one for some time now.
I have 3 installments of worppress on my server and all three
are the same, as per the page editor, Kitchen sink.
The kichen sink does not contain the following elements.
font size, font style, background color
I installed tinyMCE Advance on one site and it's working just fine, but again, the original installation did not include font size, font style, background color. If this matters at all, I am running Firefox browser.
I don't know, pulling my hair out, now.
