Hi,
I am currently facing a major problem in Confluence 6.15.9.
If I want to save new pages I get the following error message: "Unable to communicate with server. Saving is not possible at the moment" I already looked into the solutions described here: https://community.atlassian.com/t5/Confluence-questions/Getting-error-quot-Unable-to-communicate-with-server-Saving-is/qaq-p/27058
Neither collaborative editing, nor specific emojis are used.
The creation of Spaces as well as editing of already existing pages is still possible.
If I cancel the editing mode of a new page I get the following message:
com.atlassian.core.exception.InfrastructureException: org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet

caused by: org.postgresql.util.PSQLException: ERROR: relation "extrnlnks" does not exist Position: 468

Can someone help me?
