Hi,
2 years later and an upgrade to 4.1.5 and still have the same problem about thumbnailing/cache. I read all single posts on the forum about it, and most of them suggest to talk to hoster.
But what I'm supposed to ask?? I'm not sure I understand what is exactly the problem and even less able to explain it.
Thanks to help me,
Mel

What is your website?

Set 777 for all directories in /media folder too.

i had this problem in my earlier installs.
simplest solution: get a better host : P

@sam2kb : I already tried this, it doesn't change anything

@tilqicom: Yes but no... I can't. It's not my own project, it is for a non-profit organization and can't ask them to switch hosting.

I just wondering what is the problem, what I should tell them. I noticed the evocache folder (and files uploaded on backend) are created and owned by apache apache. Is it normal?
I also read somewhere it could be the "safe-mode". Is it true?
If I told the host those observations/hypothesis, do they will understand what I mean, and hope, solve my problem?

Thanks

You simply need to tell the host that you set 777 permissions to a directory and yet PHP can't create files in it. It might be due to safe mode.

Hi,
After a more or less 2 weeks of intermittent discussion with my host, they still don't find the problem. They ask me for a log file from my software, but to my knowledge, it doesn't have? Does the debug output should be helping?
thanks
