This error is fairly rare and usually only ever happens when any of these constant are defined incorrectly in the wp-config file; WP_SITEURL, WP_HOME, WP_CONTENT_DIR or WP_CONTENT_URL. Do you have any of these manually defined in the wp-config file? If you do, can you remove them and let WordPress setup them up to see if that fixes the issue?
