Can't upgrade from 1.4.6.2 - auto or manual

[Encreco]

Hi everyone,

 

We are using Prestashop 1.4.6.2 for our website, and we decided to upgrade it.

 

However, the "1-Click Updgrade" don't seem to work properly.

 

When I click on "Update now" nothing happens. I tried on IE 10, 9, Firefox (latest) and Chrome (latest).

 

And when I change the channel for major updates, the "Save" button does nothing...

 

I tried to delete and redownload the module several times and nothing seems to change.

 

Any idea ?

 

Plus, I also tried to update manually, with 1.4.10.0 version. It didn't work.

 

First of all I'd like to "repair" the auto-update module. If I can't, I'll post my other issues with manual updates..

 

Thank you.
