to uninstall the previous version, do this:
- delete all vbHome (lite) templates you created
- run step 4 from the new installer
to run step 4, load the vbHome (lite) installer in your browser like that:
vbhinstall.php?step=4
you will be prompted with the actual vbHome (lite) 3.1 uninstall. click on Continue.
you are done.
after this, start reading carefully the readmefirst.txt file. there are minor changes in v3.1 so pay attention to newthread.php file and any other details.
good look.
