Reported for: WPML Multilingual CMS 3.1.9.4

Resolved in: 3.2

Symptoms

When enabling “Use directory for default language” and selecting “HTML file” for “What to show for the root url” the HTML file is ignored.

Workaround

Select the second option and create a “normal” root page.
After doing this, switch back and try again to set the static HTML file.

It should work the second time around.
