Error Establishing Database Connection

Hello,

This is the third support ticket. I'm getting really frustrated..

I've set up the Multi-DB and i got all the databases etc all working correct.

I can head to wp-content/scripts/move-blogs.php and it shoes all green etc and i can follow the prompts. I haven't done so because my MAIN site says Error Establishing database connection. I can rename the dp-config file and all back to normal..

What i going on i've followed all training, i've followed taylor training i've done everything. I've even got my hosting providers to help me.. Is it suppose to say this ? Till you complete the move-blogs..

Please someone provide legitimate support on this plugin to help me solve this issue.
