Options & Additional Image Not Saving

Opencart version: 1.5.6.4

One one product where there are several options (over 100) I can't get more options to save or have any additional images save either. I've tried increasing levels in php.ini, but it hasn't allowed me to save those areas. This is the only product where this issue is occurring, so I don't think it's an issue with the actual installation of OC or the theme (which is a customized version of the default theme).

My server admins are going around in circles and not being much help, so any help would be greatly appreciated.

What exacly did you change about php.ini to allow it?

max_execution_time 36000
max_input_vars 1000
memory_limit 512M
post_max_size 128M

Try changing the max_input_vars to 5000 or something like that, and increase the post_max_size to 1024M

I had to have my server admin allow that access, but I was able to get it updated and it resolved my issue. Much appreciated!

( for php5) (for php7) (for php7)

set max_input_vars bigger value ,like 5000
