Forum:I can't use templatestyles features

Forums: Index → Community help

I saw that mw:Extension:TemplateStyles have been installed and want to use it. But when try to create "Template:foo/style.css" or change content model from other than sanitized CSS to it, display following error log and couldn't do these action. Is there something wrong with it? Thank you.--Kkairri (talk) 13:45, 20 June 2019 (UTC)

It looks like a bug in the extension, maybe a missing dependence, that is unable to change (or support) the "Sanitized CSS" content model. I suggest filing a bug report in ShoutWiki's phabricator. --Saftzie (talk) 20:02, 20 June 2019 (UTC)

I don't really know what that extension is enabled globally. Wikis survived for a long time before it without it, but, I believe the issue was missing composer dependencies. It works now, I think? --Lewis Cawte (talk) 11:02, 22 June 2019 (UTC)
