Hello Tom,

Thank your for reaching out! Happy to help.

From what I see, you are likely running an add-on called Zen Foundation which has reached end-of-life with the vendor.

According to their listing, Zen Foundation will only work up to Confluence version 6.14.3.

You'll want to disable your add-ons first before restarting Confluence. Have a look at How to manually remove malfunctioning add-ons for details on that.

Let me know if you have any trouble.

Regards,

Shannon
