Server won't allow me to send more than 746 Character in post

Question

i'am trying to send large blob data made in Canvas after cropping and sending it via ajax to PHP file everything works fine on localhost but on server it doesn't work. Then i found that my server won't send any data larger than 746 characters. i've updated the PHP to solve the issue

Changed the line post_max_size to 20M,80M even 0 which means no limit php.ini Changed the line upload_max_size to 20M,80M and whatsoever.

The issue still persist.

I'm posting using ajax in jquery. I've tried the sending 747 character in other forms but it failed but when i enter 746 character it worked. What might be the issue? The server is a normal vps host with ubuntu 14 server Here's the link to the phpinfo of my site http://adddon.com/info.php

Did you check the actual error message instead of blindly stabbing in the dark? — PeeHaa, Sep 28 '16 at 11:45
yep it returned 500 Internal Server Error Sorry, something went wrong :( — Shahrukh Khan, Sep 28 '16 at 11:46
Your Info shows upload_max_filesize and post_max_size as Zero. So I wonder how it even accept 746 characters. Even if it is default installation 2MB and in some install 8MB in new installation is allowed. — Sumit Gupta, Sep 28 '16 at 11:47
the php documentation says that setting it to 0 it'll send unlimited data with no limit and a guy wanted to send gigs of data so stackoverflow made this as solution too — Shahrukh Khan, Sep 28 '16 at 11:58
intiially it was 20M but it was still not sending more then that character — Shahrukh Khan, Sep 28 '16 at 11:58
still haven't identified what the specific error is forcing people to guess and ask too many questions — charlietfl, Sep 28 '16 at 12:03

Your question is tagged 'apache', but that's an nginx error message. — Rich Bowen, Sep 28 '16 at 15:11
