Hi, for me (had the exact error described above) solved it by fixing permissions. There were plugin directories under /var/atlassian/application-data/ which the user confluence could not even change to. I believe that SElinux has something to do here ... :)

This fixed part of my issue. I also had to use the next answer from Yilin Mo.

Seems a plugin issue, maybe you can try to perform the procedure :

https://confluence.atlassian.com/display/CONFKB/How+to+Clear+Confluence+Plugins+Cache

In case issue persist, I would like to advise you to open a new support ticket for help.

That did it for me, thanks!

Thank you for the response. We tried to clear plugin cache via that article, however, that was still unsuccessful. We ended up re-installing the program to fix the issue.
