Thank you for the quick responses guys.
Ryan – I did notice the md5 encryption but thanks anyway.
Michael – I’ve just followed that article you posted and changed my site url and home from localhost to the address of the web server. Had another go at logging in and it’s still doing the same thing.
One more thing, I’ve just realised I did get into my wordpress once but it seemed to have diverted me to the one on localhost. I went into the settings page and changed the address to the address of the webserver. I then tried to login via the webserver and it wouldn’t let me do it?
Would it be better to try and tidy up any changes I’ve made to my localhost version and start again with the upload?
EDIT – Just changed my locally hosted url back to localhost/wordpress and I can now get in the locally hosted admin section
