Error when upgrading from 2.3.4 to 2.6.0

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 2.5.28 and 3.4.5

Hello friends, first apologize for my English because I am using google translator ekl.
I have version 2.3.4 installed busines and upgrade to version 2.6.0, apparently everything perfect. But when you make a purchase process when you click on the "proceed with payment" button does nothing and stays on the same screen.
When reinstalling version 2.3.4 everything works again correctly.

Please indicate that you can do to update.
Thank you.

Hi,

Please download again the install package of the 2.6.0 on our website and install it on yours. It should be ok now with the new package we have on our website.

I downloaded the file again and have installed.
In localhost with joomla 2.5 works again, I do not want to update web as it is running.
Besides I am creating in localhost joomla upgrade to version 3 for later upload to web and replace version 2.5

But in version 3 of localhost now I get an error 1054 with the following.
It is this version q interests me.

Thank you.

Hi,

That issue is related to HikaSerial.
When you install HikaSerial (1.9 or newer) ; it will create new columns in your database.
If you have performed modification in your database and that column is not more there ; you can have such kind of issues.

The best in that case will be to perform an update/install of HikaSerial ; it would restore the columns in the database.

Regards,

Indeed this seems to have been the problem has been fixed.
Thank you
