When I go in to customize the crew center settings in v5, the site settings pages and such are non-existent. Photo attached here to show the only options under Site & Settings.

Revert back to ‘crystal’ skin and see if items are there.
What crew center skin are you trying to use?
If this is for a new VA or from a VA that has been using another front-end (not phpVMS), you need to use phpVMS v7 and not one of the older, unsupported versions.
Only the crystal skin is included. But I will install v7 instead. Where can I download the last non-beta release?
Latest v7 dev version can be downloaded from the releases channel on the phpVMS discord.
Be sure to read the docs (link in top menu here) and the guides.

Above links will ALWAYS give you the latest dev release, if you do not want to use Discord for some reason
