Unable to create a page by providing only title after upgrade AEM6.2 to AEM6.4
Hello,
We have upgraded our application from AEM 6.2 to AEM 6.4. In AEM author i am not able to create page by proving "title" only.
While creating page it shows loading and after a long time it is giving below error.

To debug this issue i have tried below steps
- First we have restarted the AEM author instance for rebuild all the bundles.
- We have reinstall the package in /crx/packmgr.
- On click on create button, in network tab i could see the action goes to /libs/wcm/core/content/sites/createpagewizard/jcr:content and waiting for page creation.
- We have tried to create a page via classic UI (/siteadmin), still page is not getting created.
- We found one forum https://forums.adobe.com/message/10428545#10428545 where it is saying might be network issue browser window issue. We have clear the browser cache and close the browser window then reopen the browser and tried again but still issue occurred.
- We have also tried with different browsers (Chrome, Firefox and IE11) but it was not helpful.
Can anyone help on this.
Thanks in advance !!!
Regards,
Prahlad
