Nimble builder and WPML String Translation

Good day,

I’m looking for support. I have customizr pro themplate and I’m using nimble builder and WPML. I have noticed that my site crash when nimble builder and WPML String Translation plugins are enbaled. If only one of them is enabled all is ok.

Following you will find crash log. Could you help me?
