1click upgrade fail

[Anubis2702]

Hello,

I have a problem, maybe it's a bug or maybe someone can help me.

I tried to upgrade 1.7.0.0 to 1.7.0.1. On major channel I got ajax error when downloading. On archive channel I got ajax error when uncompressing. However it worked upgrading on directory channel.

Now the problem is when I'm trying to upgrade 1.7.0.1 to 1.7.0.2. Again both first two channels (major/archive) fails, and not it fails even directory channel with this error: [Ajax / Server Error for action upgradeFiles] textStatus: "error " errorThrown:"Internal Server Error " jqXHR: "

 

Thanks for any help
