ARCHIVE – Database warning “Found row where the auto_increment column has the value 0” (v3.1.1 or lower only)
This FAQ is only valid for Maps Marker Pro v3.1.1 or lower!
When using backup plugins like BackWPup or working directly in your database via phpmyadmin you might notice the following warning:
WARNING: Result of table check for wp_leafletmapsmarker_layers is: Found row where the auto_increment column has the value 0
This is generally nothing to worry about – the table wp_leafletmapsmarker_layers was designed to start with value 0 – changing this in order to suppress the warning is unfortunately not possible, as layer 0 is used for all markers which are not assigned to a layer.
