We have tried manually updating our Mautic system from 2.7.1 to 2.10.1 (this version because of a CRM connector we are using.
We used the manual update instructions from John Linhart.
Almost everything looks good, ony issue is that when we click on contacts nothing happens. Entering the URL manually we get a manual server error.
Any ideas what we did wrong and tips to get this working again?
