Hey everytime I try to install an extension this failure appears.
What should I do ?thanks !

I Also checked System->Global Config. -> Server -> Path to Temp folder is set right and the tmp folder also exist when I´m go into FTP

Maybe problem is in access rights. Probably not in chmod , ownership is more probable cause. Your server administrator should be able to help you on that issue

I´m a little bit pissed off.
My host isn´t the problem because any other template works great however I installed it.
So I deleted all again.
Uploaded it. Set the permissions right. Install it...
So it don´t works (again).
What to do?

So I cleared it all with my host at first he said it´s nothing wrong but later he has seen the failure.
So sorry and thanks for the support.

For all who have the same problem : Let check the host if the .htaccess file is right.

@ivan.milic could it be that you are from jugoslavija?
