Problems changing theme TTW

Hi,
I tried following the instructions from the "training" website to change some plone-font-weight-* values.

I copied the Barceloneta theme to a test theme, edited there the variables.plone.less file, saved changes, selected the file barceloneta.plone.less then clicked on "Tools > Build CSS" then I got a message saying "Working..." (and citing barceloneta-compiled.css as target file) but nothing changes, the message keeps displaying with no apparent activity and barceloneta-compiled.css contents do not change.

What am I doing wrong here ?

Thanks in advance,

phep

Does your browser console show any errors?

Last night I didn't check immediately but after 2 to 3 trials the console was empty. So I just tried anew and I have some more information to give:

First, after clicking on "Build CSS" this time I had to click on a "Compile" button to launch the process ; I think I got it once last night but on subsequent tries, as soon as I clicked on "Build CSS" the "Working..." message appeared, as it does now - so it seems the "Compile" button does not show up but at the first try (the server rebooted this morning, incidentaly).

This is what I had in Chromium console (Firefox was much less verbose) :

I'll try to reproduce it on a fresh install ; this Plone instance is 10 years old and has been migrated from 4.3 to 5.1 last year. It might will convey some oddities...

Just to rule out that you do not have a unicode error

  • make a very basic less file
  • build it / CSS

If this works, try googling this forum
