Try reviewing Moving_WordPress in case you missed something.
I used the search and replace tool. To my best knowledge I did everything correctly
I will also say that I’m using 3.5.1 not 3.0, that was my mistake
Try:
– switching to the default theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.
– resetting the plugins folder by FTP or phpMyAdmin.
– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.
