Hey everyone,
Apologies for any inconvenience regarding this. Could you please try to resave your permalink settings in your WordPress dashboard >> Settings >> Permalinks even without changing anything and see if the issue will persist?
If so, please send us a message on our contact form @https://premmerce.com/contact-us/ so we could proceed in looking further into this as it seems that not all users experienced this issue when we did some tests.
We’ll look forward to your messages and to helping you with this.
