OK – so I found by searching various terms via sublime text that the sample config file included with the plugin defines the STAGESHOW_MAX_TICKETSEATS with a value, set to 8.
The sample config file says to place a file named stageshow_wp-config.php with any custom definitions you need in uploads/stageshowplus/ – which I’ve done but the override isn’t taking effect.
For now I have changed the value in stageshow_defs.php but I guess this means the change will be overridden if I update the plugin at some point in the future? Not a huge issue as I now know where to edit the value but it would be nice to know if I’m doing something wrong.
Thanks
