Hello Patrizia

Thank you for your purchase.

The Lite version needs to be deactivated/deleted, and the full version installed to be able to activate the license and use all features of the plugin.

You can download the full version by logging into our store with the credentials you received when you purchased the plugin via e-mail.

When you download the file, you can rename it, so you know it's the full version (ameliabooking-full.zip for example). Then, go to Amelia Settings/Activation, and make sure "Delete database tables" slider is not enabled. After that, go to the Plugins section, deactivate and then delete Amelia, and then go to Add New/Upload and upload the zip file. 

If you're still having issues, please provide me a temporary WP-admin (administrator) user for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. 

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course, we do not provide login data to third parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.
