I keep getting this error message when I try to create a table:
Catchable fatal error: Argument 1 passed to SupsysticTables_Diagram_Module::afterTabsRendered() must be an instance of stdClass, null given in /home/qn_test/qntest.drvxray.com/wp-content/plugins/data-tables-generator-by-supsystic/src/SupsysticTables/Diagram/Module.php on line 22
I’m on Twenty Fifteen, with all other plugins deactivated.
