Problem:
My site is showing blog posts instead of the translated homepage. No issue with the default language. Everything is configured correctly. I'm using Microsoft-IIS server.

Solution:
Make sure that there's no issue with the rewrite rules on your Microsoft-IIS server.

When using "Pretty Permalinks" in WordPress, this should be configured accordingly in the web.config file.

As a test, find a web.config file located in the root directory of the installation, open it and change temporarily its content to this default one:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
	<rewrite>
		<rules>
			<rule name="Main Rule" stopProcessing="true">
				<match url=".*" />
				<conditions logicalGrouping="MatchAll">
					<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
					<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
				</conditions>
				<action type="Rewrite" url="index.php" />
			</rule>
		</rules>
	</rewrite>
 
  </system.webServer>
</configuration>

If "Pretty Permalinks" is working fine, then everything else should work fine with the WPML plughin.
