Search feature suddenly stopped working?

I was trying to find some of my old topics via my profile. When this showed the message "No results", I tried the search feature. The same happens.

This didn't happen yesterday when I was looking over some old topics.

Is this a problem on my end, or is there a bug?

Thanks!

 

It’s a bug and Sythe will eventually check it out.
