Hi,

   when trying to add a record or update a record in a table, I get the following error when a date column is included.

[10-Aug-2021 16:33:51 UTC] PHP Fatal error:  Uncaught Error: Call to a member function format() on bool in C:inetpubwordpresswp-contentpluginswpdatatablescontrollerswdt_ajax_actions.php:316 Stack trace: #0 C:inetpubwordpresswp-includesclass-wp-hook.php(303): wdtSaveTableFrontend('') #1 C:inetpubwordpresswp-includesclass-wp-hook.php(327): WP_Hook->apply_filters('', Array) #2 C:inetpubwordpresswp-includesplugin.php(470): WP_Hook->do_action(Array) #3 C:inetpubwordpresswp-adminadmin-ajax.php(187): do_action('wp_ajax_wdt_sav...') #4 {main}   thrown in C:inetpubwordpresswp-contentpluginswpdatatablescontrollerswdt_ajax_actions.php on line 316

I have tested this on both apache and IIS and it only seems to happen on IIS. Also, I have tested this with the date and datetime input control and the on-line text input control. The issue only occurs when I use IIS and the date/datetime input controls. I had logged this as private several days ago but as I've had no response I am logging this as public in case anyone else has encountered this and may have a fix or further information to assist.
