1-click Upgrade

[sbit]

When I try to use the 1-Click upgrade it just stops in the middle & doesn't do anything else? I upgraded that in the modules before using it. It worked last time when I upgraded to 1.5.6?

In my error log I get, this does anyone know how to fix it?

Tell me, please, what to do? Is not the first day I suffer.

I have now installed PrestaShop 1.6.0.6. I want to upgrade it to PrestaShop 1.6.0.8 with module 1-Click Upgrade. But I have a module does not work. Included display errors on the page and there was this line:

Fatal error: Using $this when not in object context in /var/www/xxx/data/www/xxx/modules/autoupgrade/classes/ConfigurationTest.php on line 120

$full_report = sprintf($this->l('Directory %s is not writable'), $dir); // sprintf for future translation

Help, please.
