Was just exploring V5 by using this invisioncommunity.com site and found a few things. Might as well report here.

If you search for all members to get a member list (a trick I use on my site often) Pagination only has a next or previous button

If you search for a blank by entering space bar once or twice, you get a template error.

Thank you

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.
