First off, I just want to say that you have made a great plugin. I have had many projects where I have been in need of this functionality.
I am getting an error whenever I add a new item to my Menu in the WordPress Dashboard.
The error message is the same one as above:
Warning: Invalid argument supplied for foreach() in /PATH TO/wp-content/plugins/multi-image-metabox/multi-image-metabox.php on line 66
I have reviewed my functions.php and run it through a linter and have not found any errors in it.
Any help would be greatly appreciated.
