PHP Error

Hi,

I was trying to write some information material about the module. However I'm getting this error in the log:

I guess this is some kind of Symfony/PHP magic that is not working right. I'm no programmer and I've never reported an issue, so I hope I'm doing this halfway right. Thanks!
