Saved settings don’t stick

Hello, i have the same trouble on several site. Impossible to use this plugin ! Any Solution ? Thanks.

What is your PHP version?
My guess is that you guys are running a PHP version lower than the required and the sanitization functions such as boolval don’t exist.

Thanks for the answer. My PHP version is Version 5.4.45…

That’s quite likely, I’m on 5.4.45 too.

I’ve been meaning to upgrade for a long time, but I don’t have a backup server right now and there are A LOT of websites on the server, not easy to upgrade in such conditions.

Yea… Like I thought, you guys are running a really old PHP version.
You need to upgrade it.

Thanks. What’s the minimum PHP version needed? 5.6?

Yes
