Restoring wordpress site after URL change

Hi there,

I’ve tried moving my WordPress site from my test site to a new domain but have had huge difficulties.

I tried following the instructions on moving WP but must have made a mistake somewhere and now can’t see my original site either.

I’ve tried adding the temporary code to be able to login to the dashboard and change the URL back but it’s not working.

My website is opiyo-test.co.uk

Can anyone see any obvious answers to restoring and have any simple guidelines to moving wordpress??

Thank you!
