Update from 1.4.0 to 1.5.1

[LCP Studio]

Hi everyone,

 

I promise, I've first try to look by myself, but I think I'm really stuck now...

 

Here is my problem:

I've got prestashop 1.4.0 on a server an it always worked. I wanted to upgrade from this old version to a recent one (1.5.1) but it's not working.

I followed a document about the update (put setting.conf.php + mails + img + download + upload files in the new prestashop directory that I downloaded) and I have a blank page.

I've tried to change all the permission (install folder is in 777).

 

After that, I was thinking that it's because "it's a long way to go" from 1.4.0 to 1.5.1, so I tried from 1.4.0 to 1.4.17 (major version apparently). No more success: same problem !

 

I tried to look on the forum first and tried all the answers I found, but without success.

 

Anyone could help me ? Please :-)

 

Thanks,

 

 

Julian

Hello,

I can only suggest you a Cart2Cart service as a paid alternative. They move data from older PrestaShop versions to new versions. I understand that it is not a direct decision of your problem but if you really need to upgrade your store it is still better than nothing.
