Did you update any other plugins? This don’t seem a metabox problem, but a theme problem.
THe file to look for is: wp-content/themes/betheme 14.2/functions/builder/back.php row 918

Hello,
Yes, everything is updated. WP 5.2 and PHP 7.2.
Row 918 is:
$mfn_wraps[ $parent_wrap_ID ]['items'][] = $item;
from this:
// parent wrap
$parent_wrap_ID = $_POST['mfn-item-parent'][$type_k];
$mfn_wraps[ $parent_wrap_ID ]['items'][] = $item;
}
}
try to disable all plugins and see if it works.
If works, try to enable one plugin at time and see which one causes problems.
I think the problem is betheme 14.2 if you updated it
Hi @dv14,
As @eazy0174 said, the error occurs in a theme file. So, please contact the theme author to fix it. It’s not our plugin’s bug.

Thank you for your help, @eazy0174 and @rilwis. I’ll reach out theme.
Hey @dv14, did you ever get a resolution to this issue? Because I am having the identical problem on my site.
The line $mfn_wraps[ $parent_wrap_ID ]['items'][] = $item; is throwing the error: “Uncaught Error: [] operator not supported for strings”

@ryandiaz, Yes, we had to update the theme, php version, and some other values I recall. I pointed those issues to “WordPress Premium Support” and they fixed it.
For anyone using old version of BeTheme and encounters this error. I fixed by replacing the below code:
$mfn_wraps[ $parent_wrap_ID ]['items'][] = $item;
with this code:
if (! isset($mfn_wraps[ $parent_wrap_ID ]['items']) || ! is_array($mfn_wraps[ $parent_wrap_ID ]['items'])) {
$mfn_wraps[ $parent_wrap_ID ]['items'] = array();
}
$mfn_wraps[ $parent_wrap_ID ]['items'][] = $item;
@ryandiaz I made the suggested changes but still getting an error. Any other input?
Mine happens on line 887, not sure that matters?
Thanks

Here is the code starting on line 887 through 892:
$mfn_wraps[ $parent_wrap_ID ][‘items’][] = $item;
}
}
// $mfn_items | Wraps with Items => Sections ————————————
@ryandiaz`By the way this is for PHP 7.3

Hey @mdurland28,
Thank you for providing that extra information. I see that your Line 887 on back.php has the same code that I used to have before I updated it. You said that you made my suggested changes, and still receive the same error. Did you undo my suggested changes? If so, please do my suggested changes again, and then post all of the code in your back.php from Line 887 – 892 again.
@ryandiaz changed and still getting this error message when previewing a page in editor
