Ok I have created the databases, followed the instructions to alter the config and move-blogs files and run the move-blog script.
Whilst It run i got multiple PHP Errors on lines 140 and 141 (PHP Warning: mysql_free_result(): supplied argument is not a valid MySQL result etc.... )
I refreshed the page in step 6 and got the green table in new db against all lines that show then i noticed they all relate to the _global database and none of the others are mentioned. No errors below the line...
I checked the databases and all databases accept the original one and the new global_ one are empty.
The site does not load now it is giving database errors (you can view the URL to see these).. help i have no multi DB set up and now I cannot access the site at all !
