Description:

The issue only occurs on 7.0.x. On master, LPS-64308 rewrote this part.

1.Add "portal.proxy.path=/abc" to portal-ext.properties.

2.Setup web server, I used Apache and do the followings configuration.

<VirtualHost *:80>
ProxyPreserveHost On
ProxyPass /abc http://localhost:8080
ProxyPassReverse /abc http://localhost:8080
</VirtualHost>

3. Start Liferay

4. Access to Liferay via web server(e.g. http://localhost/abc)

5. Open settings for any portlet

6. Click "Look and Feel Configuration"

Actual result
