Resolved!

It was the actual filter itself breaking create project functionality in the frontend plugin. The following filter is recommended by the Inceptio theme developer to remove empty p tags inserted by WordPress. There are other such filters out there so beware adding them. They may clean up empty Ps content but can also break plugins.

————————-

Beware: adding empty p tag strippers, such as below, can break the wp front end plugin.

remove_filter( ‘the_content’, ‘wpautop’ );
add_filter( ‘the_content’, ‘wpautop’ , 99);
add_filter( ‘the_content’, ‘shortcode_unautop’, 100);
add_filter(‘the_content’, ‘inc_shortcode_format’, 101);
if (!function_exists(‘inc_shortcode_format’)) {
function inc_shortcode_format($content)
{
$content = preg_replace(‘/(
)\s*(<)/', '<', $content); $content = preg_replace('/()\s*()\s*(<\/p>)/’, ‘‘, $content);
return $content;
}
}

Thanks for your help on this, Nizam.

I’ll add something to this…many people need the p tag filter or their theme is messed with by the empty Ps inserted by WordPress. I just tried a different filter in functions.php instead of the one above. Fixes empty p tag in theme, doesn’t mess with “+” create project in WP Project Manager Front End plugin:

add_filter('the_content', 'remove_empty_p', 20, 1);
function remove_empty_p($content){
    $content = force_balance_tags($content);
    return preg_replace('#\s*+(<br\s*/*>)?\s*
#i', '', $content);
}

Great job Tom. Thank you for sharing it with weDevs community..

You’re welcome. Hope it helps others. Sorry for leading you on wild goose chase 😉
