I'm using gravity forms with woocommerce on http://www.personalizedshowercurtains.com. I require customers to upload high resolution image files for printing, and it works fine as long as the image file is under about 3mb. When I try to upload an image file over 10mb it processes for a while and then just refreshes the page. I've changed max file upload in php.ini to 64mb and set the timeout time to 240, so I don't think this is the issue. I've tried adding the following lines in .htaccess as I found suggested in another thread, but it returns me an internal server error message.
php_value upload_max_filesize 20M
php_value post_max_size 20M
php_value max_execution_time 240
php_value max_input_time 240
In the other thread it said that this meant I should contact my host, but I'm on a vps, and I talked to them and they said just to change php.ini in WHM and that they had no size limits on their end. I'm not sure if this is a GF issue or not, but I'm really hoping you can help me get this working. Thanks in advance.
