Hello Imran,
Thanks so much for your reply and the suggestions.
I tried 1. and 2. but the issue is still there.
The design and content of the old theme is still there. I changed the logo and a few headings, which came through as changes, but the design and the rest of the content won’t budge.
I’ve installed and activated the wp-reset plugin, so I’ll give that a go now.
Thanks again!
