Hi,
I have the problem that your Extension "Meta Box Group" is only working with old WordPress and WPML Versions. But I have to update a site and now I get the following error message, if I save a post in the backend.
Warning: Invalid argument supplied for foreach() in XXXX/wp-content/plugins/meta-box-group/class-rwmb-group-field.php on line 217
Warning: Cannot modify header information - headers already sent by (output started at XXXX/wp-content/plugins/meta-box-group/class-rwmb-group-field.php:217) in XXXXX/wp-includes/pluggable.php on line 1167
My site is running with:
WordPress 4.6.
Meta Box 4.8.7
Meta Box Group 1.1.4
WPML 3.5.0
Would be great if you have a solution.
Cheers,
Andi
