Set my rented server up for RO Oval and got this error message
Selected track requires higher host mode

What do I need to do?

Never mind, found the setting and all good.

I know you got it fixed, but include the solution so others who face this issue can see it Was it your rented server set to demo/s1/s2 mode while loading up an S3 track?

Yes exactly. RO is an S3 track and I had it set to S2. Set it to S3 and that was the solution.
