An error occurred while reading in the file

Hi,

I'm having a problem with one specific URL. I'm getting this error "An error occurred while reading in the file bla.com/search...". The weird thing is that I get the following error right after: "The error was bla.com\search\bla..." See the inverted slash?? In the first error it shows the correct URL address and slashes "/" (I've copied it and pasted it in my browser and it worked just fine), but when it clarifies the error with the "The error was..." it uses the inverted slash. Could it has something to do with the problem?

Best
