I am working my WP site with Git and because of that I have a local site, the same but on a Development Stage and again but for the Public and that’s the actual site ofc. Basically what is happening is that suddenly some Peepso (social network plugin) scripts stopped working and now the console tells me that some things are undefined. The thing is that this happens ONLY in the DEV Site, my local and public site are perfect, apart from an unique client that reported having the same issue, all people does not have any problem. Does anybody knows why is this happening or did you have a similar issue? Thanks in advance!
This is the dev site console:

This is the local site console (public site is basically the same) and those ‘left’ errors doesn’t cause problems:

I would like to understand what can cause those kind of problems and get to know how to solve it in the future.
