I cannot find anything out on the web about the trick to updating a purchased theme and not losing the theme settings.
If this was a free theme I would simply click on the Update button and W.org would update the file, and all the theme settings would be in place.
I am using Remal theme purchased from Themeforest. (Great theme!) I did not make a child theme because I have been able to do all the customization I have needed from the theme settings page.
Now there is an update. I downloaded it from the Themeforest/Remal site.
When I go to Dashboard/Appearance/Themes/Install Themes/Upload and try to upload a zip file the upload fails because there is already a folder named Remal in the Themes folder in my Cpanel.
Yes, I could change the name of the original theme's folder and upload the new theme into a new folder named Remal. But then I will be starting from scratch.
What am I missing here? How do I update a purchased theme?
