We restored the environment from backup and deployed the latest build again. It worked fine. We could not troubleshoot the reason behind the issue or what fixed it but it is working now.

I could recall some similar issue reported on Forums for AEM 6.2 as well. Forced compiling worked that time.

Please follow How to force a recompilation of all Sling scripts jsps, java, and sightly in AEM 6.4 and check this this works.

It was then some datastore corruption issue.

We installed a code package but it worked properly that time. We deployed a package on Friday morning. It worked welll. but on Sunday afternoon, it started giving this issue.

Really surprised. We reverted the packages deployed on thursday and friday but still issue persists. We have restarted the system twice after deploying old package but it is still giving same issue.

No HTML page : sites.html, editor.html, login.html is appearing.

In Friday change, We introduced listeners.js in server libs
