XF 1.5 Problem with Sitemap

[ForumUniCraft]

Recently, I do have a problem with my sitemap giving me that error each time, I try to modify something in my forum permissions or cron tasks :

This is a web server error due to incorrect permissions.

Ensure the /data and /internal_data directories are 0777 recursively.

You can do that with your FTP application by right clicking on the directories and setting the permissions.
