How would and where would I put this code?

Installation Instructions are in the readme.txt file included in vBookie.zip

Which step are you having trouble with?

This one. It was working fine for 3.5 but when I tried to upgrade to 3.6 I get errors in the database.

which db errors are you getting?

the 3.6 fix doesn't cause/resolve db errors - it's purpose is to redirect you to the vbookie event after creating a thread with the vbookie box ticked.

To change the plugin code you need to go to
Admin CP -> Plugins & Products -> Plugin Manager -> vBookie: Redirect to vbookie.php when posting new Event

then replace the plugin code as directed in Paul M's post.

I tried uploading the product-bookiehack_vbplaza.xml file, but it gave me an error of
Code:
Can someone help me out?

how do post multiple events in one thread?

You don't ? it's not coded to work that way. One event per thread.

you can have multiple correct outcomes on an event... for example check out This Thread where there 5 of the available 15 bets paid out...

My usergroup permissions for vbookie keeps going back to no whenever I set it to yes. Anyone know the problem?
