The XML entry form for the "Link directory" service has been slightly modified.
If you have overloaded the rendering of this service (pages/services/directory/directory_1.0.xsl), the theme label is no longer found in the attribute @label tag, but in the <label>
Look for the use of @label to replace it.
For example, in the "link-theme" template:
<xsl:for-each select="themes/theme"> <li><xsl:value-of select="@label"/> </xsl:for-each>
<xsl:for-each select="themes/theme"> <li><xsl:value-of select="@label"/> </xsl:for-each>
<xsl:for-each select="themes/theme"> <li><xsl:value-of select="@label"/> </xsl:for-each>
has been replaced by :
<xsl:for-each select="themes/theme"> <li><xsl:value-of select="label"/> </xsl:for-each>
<xsl:for-each select="themes/theme"> <li><xsl:value-of select="label"/> </xsl:for-each>
<xsl:for-each select="themes/theme"> <li><xsl:value-of select="label"/> </xsl:for-each>
