Hello. I must have done something wrong when I tried to upgrade to the latest version of propulsion. I just overwritten the old folder (…themes/propulsion) with the new one.
After having done that, all the templates I had created with the template builder were lost. The templates are there in the builder, but they are all empty. However the widget areas created within the templates remained, with their widgets correctly in them.
I backupped the whole site&db before upgrading so – I thought – I just overwrite the new directory with the old one and I should have everything as it was before.
