I believe this has been fixed in later versions, but if you are running Extcal 2.04 and have problems getting RSS to work, it may be due to a small error in the installer that fails to load the RSS template to the database.
xoops_version.php
change:
//Templates
$modversion['templates'][6]['file'] = 'extcal_rss.html';
$modversion['templates'][6]['description'] = '';
$modversion['templates'][6]['file'] = 'extcal_month.html';
$modversion['templates'][6]['description'] = '';
to:
//Templates
$modversion['templates'][6]['file'] = 'extcal_rss.html';
$modversion['templates'][6]['description'] = '';
$modversion['templates'][7]['file'] = 'extcal_month.html';
$modversion['templates'][7]['description'] = '';
Simply make the mod and update the module to add the missing template.
