Yes I have tried both. We use Cpanel on an ISP's server so it's easy to change settings. Elsewhere on the forum I read that php servers used a temporary area that they first loaded files to and I should set the priveledges there.
Note the error snippet "Unable to move '/tmp/phpLnjYHl' ". I also changed the settings on what I believe to be that tmp directory to no avail as well.
I have checked the documentation from WA and crawled the forum with know apparent fix.
I hope tht the support group at WA responds soon.
