Error in Performance page

Whenever I try to modify my cache settings, I get the following error:

Error: could not detect whether debug mode is enabled. Make sure that the correct permissions are set on the file /home/librairiezbook/public_html/config/defines.inc.php

Permissions are set to 0644 for that file, which appears to be normal. Debug mode is not enabled, for either the shop or the cache section. Any ideas?

Have you modified that file? Or set the permissions differently on that file? You might upload a fresh version from github.

I was thinking of doing that but it eventually disappeared by itself.

I did not change permissions (0644) nor did I modify it.

So, has this issue solved itself then?

[movieseals]

Yes, it appears so. There are a few times so far that problems suddenly pop then disappear after a few days. It is really weird.
