[TYPO3-english] RTE TSconfig magic

[ktt]

Hello,

I have RTE TSconfig, adding a new button "chMode" to hide, but it doesn't work. Previous buttons are fine. Maybe line formatting is important in it?
Cache was relaoded..

RTE.default >
RTE {
    default {
        # link to site css stylesheet
        contentCSS = fileadmin/css/rte-typo3.css
        //proc.entryHTMLparser_db = 1
        proc.entryHTMLparser_db.tags.table.fixAttrib.cellspacing.set = 0
        proc.entryHTMLparser_db.tags.table.fixAttrib.border.set = 0
        hideTableOperationsInToolbar = 1
        disableEnterParagraphs=1
    	buttons.toggleborders.keepInToolbar = 1
        showButtons = *
        hideButtons = blockstyle, blockstylelabel, chMode
<...> 

Thank you in advance,
Ktt
