I think you should be able to send a file using forum personal messages. There is a "full editor" option which allows file uploading.

You have a mess with file owners and permissions. Let's try to change file and directory permissions correctly and change their owner to apache.
First you should find a path to your website in that system report. Then you need to execute following commands:
find PATH_TO_WEBSITE -type f -exec chmod 644 {} \;
This is to change file permissions. And this one is for folders:
find PATH_TO_WEBSITE -type d -exec chmod 755 {} \;
Next change the owner to apache:
chown -R apache:apache PATH_TO_WEBSITE
After that try how everything works.
