System Eror after click on EDIT any page
Asked by 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 {#toc-hId--1244627928}
---------------------------------------------------

[![logo](https://sqf.bisimulations.com/images/logo/confluence_48_white.png "Confluence")](https://sqf.bisimulations.com/)System Error {#toc-hId-1242884905}
-----------------------------------------------------------------------------------------------------------------------------------------------------------

A system error has occurred --- our apologies!

For immediate troubleshooting, consult our **[knowledge base](http://confluence.atlassian.com/display/CONFKB/Confluence+Knowledge+Base+Home)** for a solution.
