[Jared Shute]

after upgrade from 5.9.4 to 6.15.7 admin page is now blank have tried from multiple sources and browsers. 

[Nic Brough -Adaptavist-]

Is it just the admin page?  What does the log say the server is doing when you visit the broken pages?

[Jared Shute]

I think you may have old, incompatible apps installed.  Can you run though https://confluence.atlassian.com/confkb/error-500-while-trying-to-access-some-admin-functions-noclassdeffounderror-com-atlassian-upm-osgi-impl-versions-867176931.html ?
