problemcek pri nastavitvi dovoljenj direktorijem?

Se jest z manjsim problemckom. Vzel sm si en template iz neta kao digishop, problem se pojavi pri 9 koraku instalacije. Navajam:

STEP 9: Using your FTP program, upload the CONTENTS of your Secure
folder to this secure directory. Next, change the permissions for
following directories, to allow files to be saved inside these
directories. Try chmod 644 initially, if that doesn't work, try
chmod 777 (use with caution). This is also information WE CANNOT
provide you with. Ask your network administrator, if you need help.

secure/images/products
secure/images/categories
