Many thanks for the replies, though it has not gone to plan
I followed the instructions in that I changed the directory, saved, then moved the files using ftp FileZilla.
Unfortunately I’m now left with the site not working either on the www.domain.co.uk or www.domain.co.uk/new (second one being where the wp was originally installed and working)
When i go to www.domain.co.uk i get the message
Warning: require(/home/f/a/fairlight/public_html/wp-includes/load.php) [function.require]: failed to open stream: No such file or directory in /home/f/a/fairlight/public_html/wp-settings.php on line 21
Fatal error: require() [function.require]: Failed opening required '/home/f/a/fairlight/public_html/wp-includes/load.php' (include_path='.://lib/php') in /home/f/a/fairlight/public_html/wp-settings.php on line 21
And when i go to www.domain.co.uk/new i get a 404 error page with the theme sort of showing up but all the content is missing.
When i try to log in to wp-login.php through www.domain.co.uk/new/wp-login.php i get redirected to line 21 error message at the address www.domain.co.uk/wp-login.php.
I guess one of my main concerns is that i have lost all of the pages and posts i have made for the site. Though hopefully that is still stored somewhere.
As i'm at a bit of a loss thought it best to hopefully get some adivce instead of randomly uploadeding and downloading the files to see if anything happens.
Many thanks for advice and help,
