I found the location of my php.ini file on my windows server and changed the max_input_vars line from 1000 to 3000 and changed post_max_size to 16m and rebooted my server. Now, the post_max_size changed, but the max_input_vars didn't when I check phpinfo.
I even searched my server for other variations of my php.ini file and changed max_input_users in those, as well, including php.ini.development and another one. Still no change when I look at my phpinfo.
I also thought maybe sehosin was installed, so I added the lines:
suhosin.request.max_vars = 3000 suhosin.post.max_vars = 3000
Still, my max_input_vars = 1000.
How does one change this value??
