Answer 1

same problem
but i think the problem is about the Permission of files
i have 777 permission (full permission to write, read, execute) of the parent folder and files
but not for all the parents folders:-
this is the full path
/usr2/httpd/jspapps/ashraf
i have the -777- premission of "ashraf" folder only....???!!!!
