PHP message: Slim Application Error - zend-escaper

[AndyHee]

I persistently get this Slim Application Error.

What's happening here?

Do you have a specific URL to reproduce the error? It seems to happen in the search, but the range of possibilities is pretty large.

[MrPetovan]

Ha, never mind, it crashes when you pass an empty search string.

[AndyHee]

The error is logged in roughly five minute intervals around the clock.

I'm not sure if this relates to searching.
