Thank you! I logged in and found the error. It was quite helpful, and I’ve added a countermeasure to prevent the fatal error. I do think it is still choking on some values, so I’ve added some code to output a PHP Warning. I don’t think this is fully resolved but at least it won’t crash the site, and we’ll have better error output with the next version.
Regarding the ID to class change, thank you for the heads up! I can keep an eye out for issues like that. Do you recall if the issue was the ID not being output at all? That sounds like it could have caused the error you’re seeing. If that’s true, do you remember what kind of element it was? No worries either way, we’ll be able to figure it out.
Let me know after the next beta/RC if you’re still seeing the footer color issue. I’ve worked out some issues involving Global colors so that might have resolved your issue.
Thank you!
