Fixed it somehow. Thanks for the help though!
That’s the weird thing. I tried throwing in typos, just to idiot check myself. It would return the error like this:
WARNING: Found wrong tag, remove *typo* from your style.css header.
For reasons it’s just returning:
WARNING: Found wrong tag, remove from your style.css header.
The Tag that caused the error gets returned between remove and from, but whatever is causing this error isn’t being returned.
I’ve been writing my own theme. I started from _s template, then added my own styles.
