Copy button not visible on Products page

Hi
I think I caused this problem when upgrading from Starter to Essential. My actions show that a little knowledge is a dangerous thing...!

I installed Essential without de-installing Starter as advised. I then re-imported my VM data but was told that an import had previously been completed (done when I installed Essential). In order to repeat the full VM import process, I deinstalled Hikashop and dropped all _Hikashop_ tables in the MySQL database. I then re-installed Hikashop Essential. Realising I had a lot of work to do to recover the Hikashop configuration, I used Akeeba Restore to rollback to a previous Restore point. I then tried to re-install Essential. This partly failed and I was unable to upload product photos. A Joomla debug error reported that a file could not be written to. It also prevented further re-installation of the Hikashop extension via Joomla Install/Uninstall. I repeated the Akeeba rollback to an earlier restore point (Hikashop starter)and all worked OK. I then re-installed Hikashop Essential successfully.

I now have a functioning installation apart from the Product 'copy' button not appearing. I would appreciate any suggestions as to how best resolve this.

Thanks

Bob

Thanks for the quick reply.
I have done as you suggested but the problem still remains. Do you have any other suggestions?
