Every time I am trying to upgrade on last step I don’t know why this is happening but

All template is destroyed and I am not able to

Please let me know if any body has any solution

Hi,

Are you still having issues with this?

If so, After the upgrade fails, do you see any error messages in any of the:
Suitecrm.log, upgradeWizard.log or your php/apache logs?

It would also be worth ensuring that the permissions are set correctly on the instance before upgrading, just to rule that out.

These are typically recommended as:
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload
sudo chown -R www-data:www-data .
(replacing www-data with whatever your web server user is)
