I'm running GF 1.5 and have a small problem.
I'm using a "images" field to upload an image. The fields name on my form is called "Phamplet or Leaflet"
If I upload an images with a name like "room_with_view.jpg" it works 100% and upload the image to the post gallery and I can view it
But if I load an images with a name like "room with view" it doesn't upload. It show up in the gallery but as a broken image.
It does upload to the wp-content/uploads file but is broken. The wp-content/uploads permissions has been set to 777
I have not specified any file types in the image upload field so it can not be that it is the wrong file type.
It seems that if a image file name with spaces in the name is uploaded something goes wrong.
See my form here - http://www.stayanight.co.za/load-special-offer (the field name with the problem is called "Phamplet or Leaflet" on page 2)
Note: When testing the form select "Basic" in the "What type of membership do you currently have field"
