OpenCart Community

Hi
i follow the instructions of this documentation http://docs.opencart.com/upgrading/ in order to upgrade my eshop from 1.5.5.1 to 3.0.2.0 version. Al done via filezilla and transfered to update file in public_html. Next, i try to do this step: the administrator must visit the install page. The install page is located at the store location followed by "/install" like so: www."mystore".com/install. The following screenshot displays the upgrade instructions after it finishes updating when viewing the install page.
But instead of upgrade page it shows: page not found.
Please advise
Thanks in advance

Well, but why then posting this in the OC v.2.x Section ?
And if you would have come here, before reading a Document, wich
is out of date since early v.1.5.x Version, then, you would have found
out, that NO older Version OC can be upgraded, just like that, since
most every OC uses some Extensions and custom Themes, and this
Fact makes it impossible, to ever just UPDATE anything, just by use
of that unfamous UPGRADE - Info and Code.

So, better get a Pro now, because some work is waiting to be done,
on the Server and in the Database, to make it work again.
Good Luck!
