Error while saving configuration from Felix console

[Shallu_Rohilla]

Hi, 

I have aem author set up over Tomcat as app server. However whenever I am trying to save a configuration from felix console, I am getting 400 exception. When I checked the Tomcat access logs I can see this error:

Temporary PID replaced by real PID upon save - 400

Actual exception-  "POST /aemauthor/system/console/configMgr/[Temporary%20PID%20replaced%20by%20real%20PID%20upon%20save] HTTP/1.1" 400 1127

Any help would be appreciated.

Enable DEBUG logging to error.log file on ROOT logger.

Then, try to save the config, and share what you find in that log file. Moreover, what do you see in stderr.log & stdout.log files?

Changing the logging level of the ROOT logger is tricky and often necessitates a server restart. This is also going to spit out GB of logging data.

I am using AEM 6.5 over tomcat.  Getting same error while page creation. LOGS:

Resolved this after creating new AEM. Still not able to get actual reason.

Can you try using the "AllowEncodedSlashes On" in the apache vhost config?
