New Snippet won’t save

Hey there,

I tried this plugin on a multisite install with latest release of WP 4.7.3 – and it worked fine. I’ve created code snippets on single sub-sites and those show perfectly on the place selected.

Then I installed on another multisite. Same configuration, but different plugins installed. Activate the “Header Footer Code Manager”, and it worked just fine on the principal website, but the sub-sites won’t allow me to save code snippets on every single site. I wrote all code, click save, the page refresh and the fields are empty.

What could be the problem?

Regards

E
