Hello Kevin.

Thank you for your purchase.

We haven't had this complaint yet.

Please tell me if the table looks normal in back-end?

wpDataTables is a WYSIWYG (What You See Is What You Get) concept based plugin. This means that the table should look the same both in back-end and in front-end. If your front-end table looks and behaves differently than in back-end, this usually implies that there is another plugin (or the current theme) that's changing the behavior of our plugin.

Can you try changing your theme, just to see if the issue is resolved? If not - deactivate all plugins except for wpDataTables, and check if the issues is resolved - if so, start activating plugins one by one, and after each one refresh the page again to see if the issue represents itself. Once it does you will have found the plugin causing the conflict.

Unfortunately the issues like conflicts with third party plugins or themes are always possible due to the nature of WP, and it might take significant time to investigate and replicate the issue on our side, to be able to find the source of the problem, especially when the plugin or theme is not familiar to us. 

Best regards.
