I am becoming increasingly concerned that I have muffed it!
My daughter's WordPress website shared my hosting but, when I moved to a new host (iPage), she got her own account with the same host.
I downloaded my website onto my hard drive, then uploaded it to iPage and it all worked fine. Not knowing about the complexities of WordPress, I attempted to do the same with my daughter's site - and it didn't :(
So, I have read about MySQL and have created a database on iPage using the same details as in her old WP-config file, but I can't figure out how to load it with the data. I have the full copy of the old site on the new host, but no longer have access to the old host.
I would be very grateful for any assistance ...
