Hey there jemiss, thanks for reaching out on this. It’s a little troubling if the documentation isn’t working for you. I’ll see if I can get someone to help with your immediate issues and then we’d be happy to hear of any errors or faults that you’re finding too.
For bugs and errors (including in documentation) you are invited to raise a Jira report, and this way you will be able to more easily track how things progress and when fixes are available. The URL for that is https://jira.percona.com and on that first page you’ll find some useful tips on how to report issues.
Meanwhile, I will draw the attention of the PMM team to this question. Thanks!
Could you also update this post with a few more details e.g. are you new to PMM, is it an upgrade or are you trying a new install, what environment you’re installing into and so on.
