System Eror after click on EDIT any page

[IT Ops]

Hi support,

since yesterday we had a problem with editing any page. When we want to edit any page - we get the System Error (Resume editing doesn't works).

Oops - an error has occurred

 System Error

A system error has occurred — our apologies!

For immediate troubleshooting, consult our knowledge base for a solution.

If you would like to receive support from Atlassian's support team, ask your Confluence administrator to create a support issue on Atlassian's support system with the following information:

1. a description of your problem and what you were doing at the time it occurred
2. a copy of the error and system information found below
3. a copy of the application logs (if possible).

Your Confluence administrator can use the support request form to create a support ticket which will include this information.

We will respond as promptly as possible.
Thank you!

Return to site homepage…

 You can resume editing the most recently saved draft of your page.
