I have encounter a problem activating the plugin after moving my website to an other folder on the server.
After moving the whole wordpress website to an other folder I had to reactivate all my installed plugins. When I do activate the WP Table Builder plugin I receive the message “Plugin could not be activated because it triggered a fatal error”.
Sorry to hear you are having this issue. Can you share the error message if it is visible? Also you can delete and reinstall the plugin, your tables will still be there when you install and activate the plugin again. We will investigate and try to recreate this issue, and give you an update when finished.
