I have just upgraded from 5.5 to 6.1, and am experiencing the following issues:
I am logged is as administrator. When I click on “Settings”, I get a page with only “User ‘anonymous’ doesn’t exist.” Why do I need an anonymous user, and how do I create one?
graphs are not being generated. Graph returning visits and Last visits graph display: "Open Flash Chart
JSON Parse Error [Syntax error]
Error at character 0, line 1:
0: Preparing archive: skipped, archive is before the website was created"
all widgets display “Preparing archive: archive already processed [id = 48]…” at the top. The number changes depending on the day.
visits overview is showing broken images.
How do I fix these issues, particularly since I cannot even change the settings?
