...Diagnosis
You have Adaptavist's 'Forms for Confluence' add-on installed in your instance.
Clearing plugin cache does not resolve the issue.
Adding this JVM parameter when starting up Confluence does not resolve the issue:
--jvmargs "-Dis.analytics.enabled=false"Enabling 'Safe Mode' allows you to create and edit pages again.
Cause
Adaptavist's 'Forms for Confluence' is causing this issue to occur.
Solution
Workaround
Adaptavist has proposed a workaround to the issue whereby you must set the system property confluence.context.batching.disable to 'true'. By default, it is set to 'false'.
For more information about this system property, refer to this documentation: Recognized System Properties - confluence.context.batching.disable.
Linux
Edit
<Confluence-installation-directory>/bin/setenv.sh.Find the section
CATALINA_OPTS=and add the following line beforeexport CATALINA_OPTS:1CATALINA_OPTS="confluence.context.batching.disable=true ${CATALINA_OPTS}"
Windows (starting from .bat file)
Note: These instructions are valid if you start Confluence using the .bat file. If you start Confluence using Windows as a Service, please refer to these instructions here: Configure System Properties for Windows Services.
Edit
<Confluence-installation-directory>/bin/setenv.bat.Find the section
CATALINA_OPTS=and add the following line:1set CATALINA_OPTS=confluence.context.batching.disable=true %CATALINA_OPTS%
If the workaround above did not work for you, please contact Adaptavist Support for further assistance.
