Just to contribute to this topic see following information.
Depending on host setup of apache following happens.
Most cgi and php on the server run as user nobody. So any files / folders created by user nobody cannot be accessed / deleted / created if following folder permission is set
775 for folders and 644 for files
If 777 for folders and 666 for files permissions set then scripts should be able to write to these folders / files tough leaving them open to security concerns.
If apache runs as the account owners username ( Apache suEXEC / PHPsuEXEC ) then all scripts etc should be ok to run / access /create / delete under 755 folder permissions.
How to test ?
Use your ftp and chmod following folders to 777 and delete old cache of image files from there.
- Code: Select all
modules/mod_news_pro_gk4/cache/
Change it back to 755 after your test.
Example chmod examples. Pay attention to 755 , Group and Public have no write access.

777 everyone can write as long as they have access to server as user.

See you around...
