I’ve hit a snag where when I try to update a notebook I’m writing in SWISH I get a “Permission denied. Please try a different name” error.
Previous ones I’ve done, eg https://swish.swi-prolog.org/p/Iteration2.swinb didn’t give that problem (once I learned that putting a short sentence in the “Changes” box was mandatory).
But one I’m currently working at at https://swish.swi-prolog.org/p/htdp.swinb refuses to save unless I keep changing the name to htdp1.swinb or whatever. I’ve no idea what I’m doing differently to the previous ones that worked.
Any ideas what causes this glitch?
