Hi, I've been wondering if there is something else do to to get the source maps for css enabled. I followed the instructions on the Extension page of the "LESS Module". I edited and un-commented the property "lesscss.generateInlineSourceMaps = true" within "xwiki.properties". Afterwards I restarted the server service. I also switched color themes to clean the cache. But I cannot see a change in the developer views of Chromium or Firefox. Every style still refers to style.css. At this point I also want to ask about the usage of the manual cleaning method for the cache. The documentation says that I can use the LESS CSS script service and provides a snippet {{velocity}}  $service.lesscss.clearCache() {{velocity}} But where should I put this? The section "Script Service" on the LESS Module page only has a link to the source code on GitHub. I'm still digging into the XWiki world so maybe it is just a matter of time if can figure it out. The whole velocity less scripting thing is a huge topic though. Regards, sthag
