I posted about this issue before, but have been unable to resolve it. I'm really beating my head against the wall with this one! This is my form: http://www.viralfunnels.com/squeeze-page-order-form/
Here's the issue: as you can see, I have 4 required file upload boxes in the middle of that form. I have a couple other ones (also required) that appear conditionally based on their answers to the "Yes" and "No" questions. I am using a plugin that automatically uploads my Media Library into my Amazon S3 account. Just to give you some context...
When I get entries, sometimes only a couple of those REQUIRED file upload boxes have content in them. This last time, none of them did. I am also not getting any kind of error - in the 'Entries' section, it appears like these questions just do not exist in the entries without files. The files don't appear in my S3 account or the media library; they are never referred to in my entries or the entry email that gets sent to me - it's like they don't exist!
I was told about my PHP max file size upload limit, and just got off the phone with my hosting company who assured me I have raised the limit correctly. I have also been reading some other posts about the PHP max file size upload limit, and they mention receiving some type of error message, which neither my respondents or myself has ever seen. Any idea what might be going on here?
