TYPO3 Core

when I edit text in the RTE the bold and italic buttons work as expected. but after saving the text all new bold or italic formattings disappear. there is no trace of the formatting in the html-code. the problem appears under both Typo3 3.8.1 and 4.0.

Page-TS:

RTE.config.tt_content.bodytext.proc.allowedClasses = kleiner
RTE.default {
contentCSS = fileadmin/template/main/style.css
removeTags = sdfield,font,center
removeTagsAndContents = style,script
showButtons = textstyle, formatblock, bold, italic, underline, strikethrough, subscript, superscript, left, center, right, justifyfull, orderedlist, unorderedlist, outdent, indent, textindicator, emoticon, insertcharacter, line, link, table, user, acronym, findreplace, chMode, removeformat, copy, cut, paste, undo, redo, showhelp, about, toggleborders, tableproperties, rowproperties, rowinsertabove, rowinsertunder, rowdelete, rowsplit, columninsertbefore, columninsertafter, columndelete, columnsplit, cellproperties, cellinsertbefore, cellinsertafter, celldelete, cellsplit, cellmerge
hideButtons = image
removeTrailingBR = 1
hidePStyleItems = H1, H2, H4, H5, H6, ADDRESS
showStatusBar = 1
useCSS = 1
classesCharacter = vielkleiner, kleiner, groesser, vielgroesser
classesAnchor = link
}
RTE.config.tt_content.bodytext.showButtons < RTE.default.showButtons

Setup:

config.xhtml_cleaning = all
