Tridion 9.5 Richtext area <br> in source results in not saving the Component

Question

When you switch to 'design tab' and press enter and go to the 'source tab' all <br/> are translated back to <br> and this seems to be invalid HTML and we are unable to save the Component.

It happens to all rich-text fields for all the Components.

We migrated from 8.1 to 8.5 to 9.5. XSLT did not change, and it actually uses the default XSLT that came with the installation no there is not customization done.

Answer 1

Please can you try with the following filter try to edit one of the rich text schema and compare the filter option

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
        <xsl:output omit-xml-declaration="yes" method="xml" cdata-section-elements="script"></xsl:output>
        <xsl:template match="/ | node() | @*">
          <xsl:copy>
            <xsl:apply-templates select="node() | @*"></xsl:apply-templates>
          </xsl:copy>
        </xsl:template>
        <xsl:template match="*[      (self::br or self::p or self::div)     and      normalize-space(translate(., &apos; &apos;, &apos;&apos;)) = &apos;&apos;     and      not(@*)     and      not(processing-instruction())     and      not(comment())     and      not(*[not(self::br) or @* or * or node()])     and      not(following::node()[not(         (self::text() or self::br or self::p or self::div)        and         normalize-space(translate(., &apos; &apos;, &apos;&apos;)) = &apos;&apos;        and         not(@*)        and         not(processing-instruction())        and         not(comment())        and         not(*[not(self::br) or @* or * or node()])       )])     ]">
          <!-- ignore all paragraphs and line-breaks at the end that have nothing but (non-breaking) spaces and line breaks -->
        </xsl:template>
        <xsl:template match="br[parent::div and not(preceding-sibling::node()) and not(following-sibling::node())]">
          <!-- Chrome generates <div><br/></div>. Renders differently in different browsers. Replace it with a non-breaking space -->
          <xsl:text> </xsl:text>
        </xsl:template>
        <!-- remove disallowed elements but keep its children -->
        <xsl:template match="font">

        <xsl:template match="*[not(local-name() = &apos;table&apos; or local-name() = &apos;tr&apos; or local-name() = &apos;th&apos; or local-name() = &apos;td&apos; or local-name() = &apos;col&apos;)]/@style"></xsl:template>
        <xsl:template match="span/@style">
          <xsl:if test="contains(.,&apos;text-decoration&apos;)">
            <xsl:copy></xsl:copy>
          </xsl:if>
        </xsl:template>
        <!-- remove rowspan and collspan when set to 1 -->
        <xsl:template match="@colspan[.=&apos;1&apos;] | @rowspan[.=&apos;1&apos;]"></xsl:template>
        <!-- remove well known Microsoft Word classes -->
        <xsl:template match="@class[starts-with(., &apos;Mso&apos;)] | @class[starts-with(., &apos;mso&apos;)]"></xsl:template>
        <!-- remove conditional comments that Microsoft Word uses -->
        <xsl:template match="comment()[contains(., &apos;if&apos;)] | comment()[contains(., &apos;endif&apos;)]"></xsl:template>
        
      </xsl:stylesheet>

Answer 2

The problem happens because of a cleanup script that stops the com+ "Tridion Sites Content Manager" and then deletes some log files from the system. Then it starts the com+ again. but the Running Processes under the component Services is not recycled. When I either reboot the server or manually recycle the problem is gone. Now I still have no clue on why this would result in Tidy acting like it does. changing <br/> to <br> other than it simply does. So basically now after the cleanup's I run a server reboot. but I would rather have a more solid solution. And yes the com+ needs to be stoped else it won't remove all files that need to to be removed.
