Can't modify Theme options

I have been using the theme Brixton for a while and never had a problem with it until the last update.
When I try to modify anything in the Theme options, after I hit the Save button, everything is reset to what it was before. I can’t change anything.
Does anyone have an idea how to solve this problem?


Please make sure you are using the latest version theme and your server php version is uptodate.

If the above things not solved please contact your purchased theme author, theme author will assist you.
