I'm trying to upload a 14MB PDF to my site using the Media Library. It starts to upload, then I get a message saying 'Crunching' and nothing ever happens. I've tried all I can think of - different browsers, uploading through posts or pages but nothing. I tried the old uploader but this led to an error page.
I'm replacing a 5.9MB PDF that I successfully uploaded before.
I am told the limit is 250MB for an upload to don't think it is anything to do with file size.
Can anyone help? I'd really appreciate it.
