upgrade error 1-key upgrade to 1.7

[hvrossum]

I successfully upgraded my 1.6.0 version to 1.6.1 using the 1 key upgrade module, when I wanted to upgrade to 1.7 it threw and error and killed my webshop

 

I got the following message:

 

 

 

[Ajax / Server Error for action upgradeFiles] textStatus: "error " errorThrown:"Internal Server Error " jqXHR: " "

 

What to should i do now to fix the my shop again.

 

When I try to get to the backoffice I get an http error 500

 

I am not a techie so hopefully someone can help.

The error is caused by a bug in the upgrade files in PrestaShop v1.6.0.5 that has been fixed in PrestaShop v1.6.0.6. You'll need to restore the file and database backups you made before upgrading to PrestaShop v1.7.0.5 and then upgrade to v1.7.0.6 instead.
