I'm getting a deja vu.
You have set the cookie path in your forum to be /forum/. Subsequently, Coppermine won't be able to read that cookie. Review your forum's cookie settings - set the cookie path to /
how can change the cookie path and which cookie path should i change is it for coppermine or mybb
I already told you that you need to change your forum's cookie path. I have no idea how that is done in detail, as I don't know your forum software - it's a third-party product to me. Refer to your forum's documentation or ask on the support board for your forum app if you have no idea how to accomplish this. Coppermine needs to be able to read the cookie that is being set by your forum. If that cookie is only readable for applications that reside in the folder /forum/ (seen from the web root), then coppermine won't be able to read that cookie, as it doesn't reside within that folder. You need to change this, i.e. your forum's cookie path needs to be set to "/" (witout the quotes), i.e. just to the web root. If this will be the case, both coppermine as well as your forum will be able to read the cookie, which is what we're trying to achieve here.
when I go to login to the gallery, it redirects me to mybb to login which I do and it says it worked fine then it redirects me back to coppermine and it still shows me as not being logged in.
The re-direction to and fro is expected behaviour and exactly how the bridging mechanism is supposed to work. The fact that the login you performed in your forum doesn't stick in Coppermine is caused by the fact that Coppermine can't read the forum's cookie for reasons explained in the above quotes.
Relative path to your bridge app's config file: ../forum/inc (public_html/vehiclecommunity/forum/inc)
Decide for one. The first one is a relative one, the second an absolute path. As you're requested to enter the relative path it should be obvious which one to use.
Cookie name or prefix: .vehiclecommunity (domain) /forum/ (path)
As suggested above, that's the reason for your issues. Fix that (in your forum).
Use post-based groups?: ? I'm not sure what this means
Look it up then:

Your gallery name here as gallery name shows that you haven't bothered to go to your gallery's config at least once and perform the needed edits there. Do so
now!
