Try to recompile the JSP files using the below document:

https://helpx.adobe.com/in/experience-manager/kb/How-to-force-a-recompilation-of-all-Sling-scripts-j...

Also, check if there are multiple jdk installed on the system, if yes then try to remove all except for the one you want to use and then check.

[binoyp]

It doesnt open up any pages,but instead shows a page not found error and redirects to /system/console/bundles

[binoyp]

The jdk was found to be the cause of issue. I had 8 and 13 on my on system. Uninstalled 13 and restarted the instance. Issue got resolved

@binoyp 

If you don’t have important data in localhost then delete QuickStart and re-run the server.

[ChitraMadan]

Hi @binoyp ,

Could be an indexing issue, try to remove the index in /crx-quickstart/repository/index and restart the instance.

[binoyp]

Hi All, 

Issue got resolved when i unistalled jdk 13 from the programs list and pointed the java path to the existing jdk 1.8 folder. 

Thanks for the help
