I have a problem uploading images larger than 1MB through ad attachment section. I have changed the classipress setting -> listing to allow up to 10MB, but still my 4 MB image doesn't upload. The error I get is that my image exceeds the size limitation of this field.
I know I don't have upload issue on my server and Wordpress site because I can upload large images right from media upload panel. But not when I am composing new ad and use the file attachment section.
