I am using the MB Custom Table plugin and its Model feature. However, the following error gets displayed in the backend:
Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /home/***.cloudwaysapps.com/***/public_html/wp-content/plugins/mb-custom-table/src/Model/MetaBox.php on line 70
After adding the sample code to create the custom model as in the documentation https://docs.metabox.io/extensions/mb-custom-table/#custom-models
I only see the error one time and everything works as well. However, I will report this issue to the development team to fix it in future updates.
