Doesn’t work for homepage (multisite)

Hello,

I have a multisite website with the address https://exmaple.com and https://exmaple.com/pl

On the main page the plugin works very well but there is a problem on https://exmaple.com/pl because it doesn’t work for the homepage. For ex. https://exmaple.com/pl/product/ works good but for https://exmaple.com/pl doesn’t work.

I checked the database and if there are problems on my site, but everything is fine so the problem must be in the plugin.
