I am trying to: edit a custom post type with a file upload box. I have filled in the postmeta field earlier using php, the url is correct but it has a space in it and now I can't update the record because it gives an error:
"Please enter a valid URL address pointing to the file."
Is the problem having the space in the filename? Can I
Now, regarding the file, I'm not sure but no system should allow space in filename, its not valid at all. Maybe you used PHP and did not replace the space with dash or underscore. You will have to correct that mistake by updating the database table rows where the filename is stored and replace space with dash or undersocres.
