Plan to upgrade error

[Elmar Schulte]

Hi,

I would like to upgrade from version 7.2 and have started the "plan to upgrade" function.

There I always get this error message: "Looks like we're having trouble retrieving some information. Please refresh the page".

Systemhealth is green.

Does anyone have an idea where i can get more information on this?

Regards,

Elmar

Problem was in Modul "pre_upgrade" and now solved by updating to the last version of "Atlassian Troubleshooting and Support Tools" (Manage Apps).

What page are you looking at?

It's on Admin general settings page: "Plan to Upgrade"

In the /var/logs/atlassian-confluence.log I've found these messages according to the web request:

I was heading for the logs next, so it's great that you are way ahead of me!

Unfortunately, that's a deeply buried problem, and I don't recognise it and I can't place where it's coming from.

I think this needs to go to Atlassian support over at https://support.atlassian.com/contact
