Hi,

We suddenly started getting the below page when opening Confluence..

Any idea how we can resolve this?
Here is the atlassian-confluence log file: https://mega.co.nz/#!st5jGDxA!Qk_xRXdrIYcaFX4Sv7A-5tUskl_AaRUPj94ZQ_SZt7w

Hi there, we've seen some cases similar to this and the most common cause to this issue is related to file system permission. You can see some details in this other question: https://answers.atlassian.com/questions/56733/confluence-suddenly-unusable-java-error

I hope it helps.

Cheers

Thanks, saw that one.. We are running Confluence on a Windows Server..
Do you know how the procedure is there? (I'm not the one who installed it, and am quite unfamiliar with the inner workings of Confluence.. Unfortunately.)
