I think using a program like Beyond Compare is very helpful. Eg I can just run a predefined session in a couple of seconds and see the differences between local and remote files. (In this case, the contents of grey folders are equal, red contain one or more different files and purple contain files missing on one side or the other.)
I had the same issue using toNumber(), where the numbers disappeared completely after a Wappler update. It was a while ago, but I think it was due to different versions of dmxFormatter.js.
@TomD thanks for that. Didn’t know about Beyond Compare so will take a look. I’ve had a couple of errors with dmxFormatter.js and wondered if the files on the server are up-to-date.
