Created brand new project, and installed v7.6.6 to test.

Optimus.Core v1.4.0 installs fine, no problem.

Optimus.Providers.Less v1.3.0 hangs half way through the install for more than 5 minutes, Refreshed the backoffice (package seems to be installed). Dlls are in the bin

• Optimus.Providers.Less.dll
• BundleTransformer.Less.dll
• BundleTransformer.Less.resources.dll

Web.config does not seem to be edited correctly

• Missing (add fileExtension=".less" assetTypeCode="Less")
• Missing (add name="LessTranslator" type="BundleTransformer.Less.Translators.LessTranslator, BundleTransformer.Less") amongst other things

Creating new bundle with 3 less files in, file 1 imports file 2 and 3. This gives me a YSOD immediately (error: "These assets are not style sheets: /css/sheet1.less, /css/sheet2.less, /css/sheet3.less").

If i add in the .less file extension, that fixes the YSOD.

Writing normal css in any of the files works like it should, although the files are not actually bundles (as i discovered when I loaded the site with network devtools opened, it still counts 3 files downloaded, instead of 1 bundle file).

Writing less in any of the files (e.g. setting a colour in a variable, and using that variable) does not work.

Thanks in advance.
