 * The tables which are created can’t be loaded on the page. Also, I can’t even 
   edit them. I get an permanent Error:
 * “Error
   You are trying to load a table of an unknown type. Probably you did not
   activate the addon which is required to use this table type.”
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-while-loading-tables%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hello,
 * This error usually happens when **the Premium version is not active** (or was
   replaced by the Lite version), so tables that were created with Premium-only 
   features show up as an “unknown type”.
 * Please follow this guide, which explains the cause and the fix step-by-step:

 * I can also see you have a Premium license, so if you still need help after following
   the steps above, please open a Premium support ticket here (so we can assist 
   you properly):

 * Please note: This WordPress.org forum is only for wpDataTables Lite/free support,
   so for any Premium-related issues, please use the Premium support channel.
 * Kind regards,
   Milos
