Homepage keeps disabling

Hello,

I have a recurring problem regarding my homepage not being recognized anymore by the system, leading to the website not working anymore.
As soon as I re-save the homepage, the websites works properly again.

I can’t find anything relating to this problem in the error log of the website.
Is there anyone who has been having the same problem or anyone knows how I can prevent this from rehappening?

System Information
MODx Revolution 2.0.7-pl (traditional)
PHP Version 5.3,
MySQL Version 5,
pdo_mysql is installed,

If it’s anything related to this post:

Thanks for the response, i’ll update the system and hope it’ll work
