 * Hi,
    When I try to add a new field group I first get the response, that no changes
   were found and then I get redirected to a 404 page. in the debug log I get the
   following WP Database Error:
 * [Unknown column ‘productmeta_categories’ in ‘field list’]
    SELECT productmeta_id,
   productmeta_categories FROM oetyn_nm_personalized WHERE productmeta_categories!
   = ”
 * Can you please have a look at it?
    BR, George

 * Hi,
 * it seems you have a very old version installed, Please do this:
 * 1. Make sure you have latest version installed.
    2. Deactivate then activate 
   the plugin.
 * I hope it will resolve the issue.
