Can't create new pages , site area is blank, Warnings and errors in the logs

Hi, 

I'm running:

Confluence 7.1.1
Apache 2.4.29 as reverse proxy providing http redirected to https
this is across 2x Ubuntu 18.04.3 VPS.

I'm migrated to new servers, by installing a clean install of Confluence and restoring the backup from the original server. The Apache config we copied over with the required host name changes where required.  

Currently I can browse existing content fine, but when I go to create a new page, the site goes blank. 

I'm seeing the following warnings in the catalina.out log

"08-Dec-2019 10:29:13.402 WARNING [http-nio-8090-exec-9] com.sun.jersey.spi.container.servlet.WebComponent.filterFormParameters A servlet request, to the URI https://www.linuxpro.co.nz/rest/spacetree/1.0/spaces, contains form parameters in the request body but the request body has been consumed by the servlet or a servlet filter accessing the request parameters. Only resource methods using @FormParam will work as expected. Resource methods consuming the request body by other means will not work as expected."

and the  /var/atlassian/application-data/confluence/logs/atlassian-confluence.log, when I click the create button:

Please advise where I may have gone wrong in my configuration or the restore of the backup that may be causing this issue.
