Front page and other page layout broken - by SBB

I can confirm that the WPML issue was separate – WPML 4.5.11 version has issues with WP 6.1, but now we have updated WPML to 4.5.12, confirmed to work with WP 6.1 and content still doesn’t show.

Even when we deactivate all WPML plugins, content doesn’t show.

At 1am CET on the 7th of November, we have updated these:
– WordPress to 6.1
– X Store theme + X core plugin to their latest versions
– plugins:
GDPR Cookie Compliance
MC4WP: Mailchimp for WordPress
Really Simple SSL
W3 Total Cache
WooCommerce
WP Maintenance Mode & Coming Soon

Neither of these plugins should interfere with WPBakery page builder displaying content, so it still seems like an X-Store issue.

This is the error we see, does this mean anything to you?

Uncaught TypeError: Cannot read properties of undefined (reading 'currentTheme')
    at window.vc_rowBehaviour.window.vc_rowBehaviour (js_composer_front.min.js:10:9014)
    at window.vc_js.window.vc_js (js_composer_front.min.js:10:659)

Only happens when the XStore Child theme is activated (even a fresh new one I downloaded from your Downloads section, no modifications).

Seems that JsComposer (WPBakery builder) doesn’t know how to read your Child Theme?

One more thing I found out:

our original X-Store Child Theme had this function in functions.php:

//Remove Query Strings From Static Resources 
function smartwp_remove_query_strings_from_static_resources( $src ) {
  if( strpos( $src, '?v=' ) ){
    $src = remove_query_arg( 'v', $src );
  }
  if( strpos( $src, '?ver=' ) ){
    $src = remove_query_arg( 'ver', $src );
  }
  return $src;
}
add_filter( 'script_loader_src', 'smartwp_remove_query_strings_from_static_resources', 999 );
add_filter( 'style_loader_src', 'smartwp_remove_query_strings_from_static_resources', 999 );

// Add mailchimp integration
add_action('wp_head', function() {
	?>
	<script id="mcjs">!function(c,h,i,m,p){m=c.createElement(h),p=c.getElementsByTagName(h)[0],m.async=1,m.src=i,p.parentNode.insertBefore(m,p)}(document,"script","https://chimpstatic.com/mcjs-connected/js/users/ba7e51eafdcb61b2943699529/cbf3f511c5104a42d1d457e3e.js");</script>
	<?php
});

Which also causes the same issue.

When removed from functions.php, and your Remove Query Strings From Theme Static Resources is turned on, the same issue.

Basically, your theme or jscomposer doesn’t like query strings removed for some reason.

Hello Rose,

Tomas here. Earlier message was written by developer who help us to maintain, keep page updated. He could not know that part of the code wasn’t originally part of the function.php i guess as he wasn’t working with us back then. 🙂

But I have also not explanation, how “//Remove Query Strings From Static Resources ” got there. We have contracted Kraken for speed automatization in the past, maybe was added then. Either way, I disabled Remove Query Strings From Static via menu, enabled Total cache and autoptimization and seems it works again. Code for cookie accept I will have to ask someone to check.

One things till not work – instagram slider at bottom of page. It gives error “Error: Undefined error”. Could you please advise?

Thank you,
Tomas

Hello Rose,

Apologize for late reply.

Yep that helped and works. However seems only pictures displayed are only where is one photo and seems if there is album it don’t show despite check box at option “Show everything except album and video posts” is not checked.

Any trick for that?

Thank you,
Tomas
