Project won't save

I'm using a windows machine, using SNAP! version 7.3.0

I'm trying to save a very simple project and it won't.

First I got this message:

So I tried again and got this message:

And complicating the matter, several of my students are having a hard time loading their projects. They get an error about " '=' in the attribute." (sorry about the lack of specificity here; I'm trying to get one of them to send me a screenshot of their error code.

Considering the recent post about not being able to load a project, I'm wondering if there is a bigger problem.

Any insights?

Jens will fix this

The issue isn't fixed yet for me. When trying to save, it says "Project could not be saved. Please use the Snap! site, not scripts." Then when I try saving again, I get an unexpected error: "attempt to perform arithmetic on local [STRING] (a nil value)"

Are you on snap 7.3.1? You can check by clicking the snap logo, then about.
