Whenever I want to answer some questions on Stack Overflow, I rely on this FILTER that I've made in Stack Exchange.

But now, it gives me the following error every time:

Oops! An error occurred while fetching questions for this filter.

Detailed information about this error has automatically been recorded, and developers have been notified

This has been going on for quite some time (more than 2 weeks) and that's why I decided to post it here, what should I do?
