I'm using Pods as my custom post type and attempting to generate a data table for hike data using the 3rd option (generate a query to WordPress database). I currently have two rows. My experience has been that I can get a table generated in under a minute if I select only 7 fields. When I try 8 (the 8th one has the same datatype as the 7th one), I give up after 30 min. (I'm running locally on a laptop with an i5-25 processor and 4GB memory.) Eventually I'll need 10 fields for this table. I'll also need to be able to create a schedule that has foreign keys for hike, group, and user.

Is there a field limit for a query to the WordPress database? Is there a conflict with WP version 4.9.1 (the latest)? Is it possible to get a copy of the query that your software generates? Any suggestions? 

I'm running WordPress locally on my laptop using xampp (no external server). I have not installed mod_security. Where do I locate the console log you mentioned? The only error message that I've seen from wpdatatables is in red that says it wasn't able to save the table (this is after I give up after 30 min and click on another place on my dashboard).

By the way, I haven't yet seen any auto updates for your plugin.
