Problem with update

-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.8
-- PHP version -- : 7

Hi,
before updating my working site from 2.6.4 to the latest 3.2, I was trying to update on my localhost Wamp. This is the error:

Error

There was an error uploading this file to the server.
Maximum PHP file upload size is too small: This is set in php.ini in both upload_max_filesize and post_max_size settings of your PHP settings (located in php.ini and/or .htaccess file).

Unable to find install package

Further. When updated, are the language files and the list view changes I made before like listing.php changed, or can I just overwrite them with my old listing.php for the view I had before? (also the show_aditional.php and show_products.php and shipping.php and view.html.php tc.?)

Thanks and regards

Thomas

Hi Nicolas,
thanks for your reply.
As I am on 2.6 and want to upgrade to 3.2, the main question now is, is it ok to manually upload my old language and listing php files after the upgrade, even its from 2.6 to 3.2? To be precise, those files wont destroy the new type of shop script or?
If that's ok I can proceed without worries.
For the future I will follow the recommended way of doing changes.
Thanks again and regards
Thomas

PS: Oh btw, will Alpha User Points still work under 3.2?

I will try as you have suggested. Thanks a lot !

Hi,
I increased both as shown in the error message:
Maximum PHP file upload size is too small: This is set in php.ini in both upload_max_filesize and post_max_size settings of your PHP settings (located in php.ini and/or .htaccess file).

Both to 8M

Still the same error

Regards and thanks for your help
