okay I found that I needed to add "$step = get_input("step","get");" after main.inc.php
I'm not sure if it worked though, it "finished" step 10 with this message. Seems to me there was one more table that needed to be altered but I have no idea:
Changing the method in which sticky posts are tracked...
Adding a table for storing a que of display name changes...
SQL ERROR: Unable to do_query: CREATE TABLE w3t_DisplayNames ( D_Entry INT(9) NOT NULL AUTO_INCREMENT PRIMARY KEY, D_Uid INT(9), D_DisplayName VARCHAR(255) )
Table 'w3t_displaynames' already existsDone
