Hi Rich
Firstly, sorry for not getting back to you sooner. I’ve been away for a few days …. no internet …. no phone … etc.
The “Sorry you are not allowed to access this page” is probably a WordPress permissions issue. Generally this is because you have tried to access a page that requires you to be logged in when you are not, or that the user does not have sufficient permissions.
If StageShow has disappeared from your Administrator menu, then the plugin might not be installed (or is corrupted) or there could be an issue with the capabilities of the logged in user that means the user cannot access the plugin admin pages.
Finally it is unwise to publish license information on a public forum. I’ll send you a new one, along with the latest StageShow archive by email.
