Hello,
I noticed a bug with multisite and route prefix. Lets assume this configuration :
- 2 language, french and english
- no route prefix for french, /en prefix for english
- Create a homepage with url /
The /en url will works well and display your homepage, but the / only will redirect you to /fr and display a 404 error.
It seems it only occurs for homepage, cause all others pages works well without the prefix.
