Hello Milos,
Thank you for your assistance.
This is the free version of the program, and my first time working with it. Other that this error message, everything seems to work just fine.
Front end (when loaded) and back end are both functioning properly.
I created a new page, removed all of the headers, footers, widgets etc., put in only the wpdatatable shortcode, and still have that error message.
Will try deactivating plugins and switching themes a little later (off hours).
I’ll keep you posted!
This is the issue across several pages, and our fund raiser runs multiple weeks.
Thanks!
