What version and service pack are you running ?

Can you Invalidate Caches then Rebuild Libraries [1] and give it a try in private browser ?

Definitely, We are running on AEM 6.5.4

Was it working before? Did you recently install SP4 for AEM 6.5.x?

[nandini559]

We have recently installed AEM 6.5 along with SP4. Since then it doesn't work.

[berliant]

We already got a similar issue from another customer. Most likely SP4 did not update all required bundles to versions that SP4 expects. You can try to re-do SP4. Get a backup of the previous version, do re-indexing and install SP4. If it's still an issue then open a support case. It's not a trivial problem.

[nandini559]

sure will try to do so and verify if it works fine, appreciate your quick help.

@nandini559 ,

Two Things

1) If you have installed the Service pack recently-There might possibilities that you core package affected and its not Active state. Please verify it and try to restart the AEM. 

2) If the issue persist, then uninstall the SP and install it again with other browser except chrome and see all bundles are getting Active state or not.

Once your all bundles are active then you good to go.

Let us know if its works for you.

Happy Coding
