I found the problem (I used the complete text in my profile and saving while stripping it continuously
)
It was in the text "phone numbers, " in the application Treepad.
I removed it and could edit the page.
Original text of treepad (I only removed "phone numers, " on the wiki).

I also added your text already.

)
