TOPIC: No button labels after upgrade from Comment 4.18 to 4.19

After upgrading from Comment 4.18 to 4.19 the button labels are no longer displayed. Instead the variable names are displayed, e.g. . * {_JOOMLACOMMENT_ADDNEW}
* {_JOOMLACOMMENT_SEARCH}
* {_JOOMLACOMMENT_RSS}
{_JOOMLACOMMENT_COMMENTS_TITLE}

Hey Andrew - are you using a custom template? You will need to update it.

Your question pointed me into the right direction. I've fixed it. The problem was that in the process of upgrading, the 'use standard template' selected in the layout tab got lost. After I reselected it, everything was fine again. Thanks for your help.
