We updated above file: /plugins/content/loadt4pagebuilder/loadt4pagebuilder.php
Line 54:
if ($context === 'com_content.article') {
$article->text = "<div class='jpb-page'>" . $frags[0] . $frags[1] . "</div>";
} else {
$article->text = $article->introtext;
}
change to:
if ($context === 'com_content.article' && count($frags) > 1) {
$article->text = "<div class='jpb-page'>" . $frags[0] . $frags[1] . "</div>";
} else {
$article->text = $article->introtext;
}
Kindly check.
