Just Can't Export Products To Csv

I just can't make it work. The error log says Permission denied, meaning the cart tried to write the file down but it failed. Tried with 777, nothing. Ownership all ok (sitefolder:sitefolder, that'd be it?). Went through all threads but couldn't find anything that works. Just blank page. Not a size issue, doesn't work with export customers as well and there's only a few of them.

Help!

Hi

As far as I'm aware folders should be 755 and files 644

Yes and I tried even with 777 but the backend still can't write down CSV
