Settings Not Saving

First, I want to say this is a very good plugin and your support and response times are excellent. I know I’ve posted quite a number of items but I still believe this is one of the better plugins for its purpose.

I seem to be having an issue where the settings are not saving. I noticed it predominately after doing the latest update of your plugin.

Here is a video of the issue:

I am using W3 Total Cache as well as WP Optimize. During the video above Total cache was disabled completely and all caches purged prior to the screen recording.

I also recently replaced the grid.min.js file based on the autoscroll request I made previously. Don’t know if that has affected anything or not.

Thanks in advance.
