[TYPO3-RTE] my text is not underlined

[Darko Jr. Gonzalez]

Hello

I entered RTE.default.showButtons = * in Page TSConfig for one 
particular page and the editor showed me all the buttons. But I cant get 
to underline my text. I actually select it, hit CTRL+U, it is 
underlined, but then the <u></u> tag is stripped in the frontend and 
this text is not underlined. I am puzzled why bolding or making the same 
text italic works, and when I try to underline it, it doesnt work. I 
dont see anything in my CSS either that could be stopping it from being 
underlined..

Thanks for looking

Regards
Darko
