I found the Solution:
Create a folder in yourWordpressSite.com folder called “tmp” and access it with 777 also a folder “static-files” with 777 access like the following:
yourWordpressSite.com/tmp/static-files
————————–
Root/
| – yourWordpressSite.com/
| | – tmp/
| | | – static-files
| | + wp-admin
| | + wp-content
| | + wp-include
| + Bla/..
| + Bla/..
————————-
then in your simply static/setting/advanced/ => change the Temporary Files Directory to: ../tmp/static-files/
dont forget those two dots.
