Hello,
I tried the latest 1 click upgrade from 1.5.2 (clean install) to 1.5.6 and I get the error [Ajax / Server Error for action unzip] textStatus: "error " errorThrown:"Backend fetch failed " jqXHR: " "
So to next step:
I manually uploaded the 1.5.6 files in the folder admin/autoupgrade/latest and in expert mode I selected chanel 'local directory'. Is that correct?
Under that selection it still points to the prestashop zip file and it does not let me type the version under "Please tell us which version you are upgrading to (1.7.0.1 for instance)", the field turns yellow.
I saved the setting in expert mode.
Result: -> Same error, but why does it want to unzip while all files are in the latest directory?
I see many posts on this forum but no answer. I think one click upgrade is making a mess out of it.
Please advise
