I was able to resolve this issue with the help of one of my programmers. Here is what made it work:
* ./alfresco.sh stop
* killall -9 java
* rm -rf ./alf_data/*
* Drop the "alfresco" database
* Create a new alfresco database
* ./alfresco.sh start
If you run into a similar issue, please try the above. If it does not work, I'll be glad to share with you my config files.
Good luck.
