I installed the multi-db on a new WP-MU site. I did the whole 4096 db's (I am planning something very large) but once installed I had to change a line in Fix-DB-Encoding to the correct location of wp-load.php.
However, once it loaded I always get:
WordPress can automatically look for some common database problems and repair them. Repairing can take a while, so please be patient.
Basically it seems to be locked into repair mode. Anything I can do to avoid this? It seems to cause a lot of issues...
All the best
