Matt’s correct, there are no timeout settings in vB cloud. Would you mind giving his other browser idea a go and let me know what the results are?
As an aside, apologies for all the issues you’ve been having. That permissions issue turns out to be a strange bug with the UXpert user group that you were in. I have reverted you to a Gold Member while I figure it out. vB are a little slow on responding to my help tickets atm, but I’m on it.
