Hello -

I am getting the following error whenever I try to save, edit, publish, or preview new or existing pages.

PHP Fatal error:  Uncaught Error: [] operator not supported for strings in /nas/content/live/trusting/wp-content/themes/betheme/functions/builder/back.php:918\nStack trace:\n

The corresponding code on line 918 in back.php is:

$mfn_wraps[ $parent_wrap_ID ]['items'][] = $item;

I believe this is related to the moving from PHP 7.0 to 7.2 on my wordpress host (I cannot rollback to 7.0 due to host restriction.

WordPress Version: 5.1.1
PHP version: 7.2.20-2
BeTheme version: 14.3

(I understand this is not the current version of BeTheme, however, the original developer my client hired to deploy this site did not create a child theme and instead extensively modified the theme core code itself.  I am working to upgrade the theme to the current version, however, it will take a good deal of time to get the custom code working.

Please let me know if anything can me modified in the meantime.

Thanks -

Steve

    Hello Steve,
    your theme is not only outdated, it is ancient. Please update. If you have a child theme, update only the parent theme, as always. This will ofcourse also need changes in the child theme since it uses most likely outdated fucntions etc. We cannot be sure what custom code the other developer inserted.

    It is best to make a copy of the website, host it on a subdomain and update it there to see what happens.

    We suggest you disable all of your plugins and update the parent theme via FTP.
    Remove the old theme folder and install the newest version.
    thanks
