Cant update theme pages using Page Builder

conversationlab

We are currently migrating our site from php 5.6 to 7.2 as our hosts have set a fixed end of life for this.

Most features are intact, however when updating posts using muffin builder the site breaks the existing layouts, this largely is due to a

Fatal error: Uncaught Error: [] operator not supported for strings in /XXXXX/wp-content/themes/XXXXX/functions/meta-functions.php

$mfn_items[$newParentSectionID]['items'][] = $item;

We resolved this by amending this to:

$mfn_items = array();

$mfn_items[$newParentSectionID]['items'][] = $item;

However when we update or insert a post now the layouts are breaking. Any thoughts on how to fix this urgently?

Hello,

Did you update the WP and BeTheme too?

It's very important to make them work fine with the PHP 7 version.

Thanks

I only updated WP. Our BeTheme installation is customised. Would you suggest adding a new theme, then taking it from there?

You should customize only the child theme. If you cusotmized the parent theme then it will lead to problems in the future because you cannot update the theme. We suggest you contact the web developer who built it and transfer the changes to a child theme, then update the parent theme.

thanks

The web developer who built it was very inexperienced and has customised the parent theme and not the child, I now have the task of cleaning up his mess.
