Avia Layout Builder not working with Plugin Popup Maker

Hi there

We’re noticing an issue with compatibility between the Enfold theme Avia Layout Builder and plugin Popup Maker.

We recently updated the website and the code in functions.php below no longer executes.

// Add Avia Builder to Popup Maker
function avf_alb_supported_post_types_mod( array $supported_post_types )
{
$supported_post_types[] = "popup";
return $supported_post_types;
}
add_filter('avf_alb_supported_post_types',
'avf_alb_supported_post_types_mod', 10, 1);

WordPress 5.2.1
Popup Maker 1.8.6
*^ Works*

Upgrading to WP 5.2.2
Popup Maker 1.8.10
broke the functionality
(renders nothing, blank)

Below is the response from the plugin creator in terms of compatibility.

“We did change a few things between those versions, but it indicates that they are likely doing something in an unconventional way or one that simply wasn’t considering shortcodes being processed in the head.

If they are echoing or printing inside the shortcodes and expecting it to render immediately it won’t. But according to WP shortcodes should never do anything but return a string, never echo/print, so we can’t account for that, they’d need to correct it.

If they are not registering their shortcodes until after init they may not get rendered properly. Again WP says they should be registered immediately, not late, since plugins get loaded before init, and we process shortcodes in wp_head which comes after init, as long as they are done by then it won’t be an issue, if this is the problem they just need to adjust when they register their shortcodes.

Otherwise let them know this is how we handle it, see what they think may be going wrong.

1. In wp_head before wp_enqueue_scripts we process all popups that are targeted to the page being loaded.
2. Process all loaded popups content through do_shortcode, storing it for rendering.
– We capture the output if anything is echoed since we are in the head we can’t allow that to happen or it will generally break peoples sites from incorrectly created shortcodes.
3. In wp_footer we render the popups using the content processed in the head.”

It looks like Enfold may need to coordinate and cooperate with popular plugin makers to ensure compatibility with plugins like this one in a future update.

Please advise, appreciate it.
