Open the file “eventcalendar3.php”, go to line 571 (approximately) and look for this piece of code:
if($post->ec3_schedule)
{
$schedule=ec3_get_schedule('%s; ',"%1\$s %3\$s %2\$s. ",'[ %s] ');
$text=$schedule.$text;
}
Then, apply // comment and your code will like like this:
if($post->ec3_schedule)
{
// $schedule=ec3_get_schedule('%s; ',"%1\$s %3\$s %2\$s. ",'[ %s] ');
$text=$schedule.$text;
}
