I have a Contact Form 7 form on a testimonials page of a website that works perfectly, unless I try to upload an image that is larger than 1mb. I have upped the max size to 3mb and the upload still fails saying "Failed to send your message. Please try later or contact the administrator by another method". I read a lot of other forum threads and none seem to figure out my problem. I tried using "3mb" and also converting to bytes with no difference. Files under 1mb upload just fine but a photo exactly 1mb fails regardless of my max file size. Host max file size is 10mb.
Also, I have "Contact Form to DB Extension" plugin that saves the submissions to the database. Even though the email send fails, the submission actually saves to the database! I am completely boggled.
Thanks for any help.
