I have a bilangual website in: nl & fr. I use Weglot (translation plugin) & Rankmath.
Yesterday, I updated the wegblot & rankmath plugins with the latest versions.
For one or another reason, the ‘fr’ href url broke & gives a 404 error. (I do not know if it has to do with the updates or if it was there before the updates).
In the French url, there is ‘reserver-gout-dailleurs’ & this is not on correct. (reserver-gout-dailleurs was an old FRench slug). This slug appears in every page except from the HOME page.
This used to work perfectly in the past. I do not know when this changed & what is the cause.
I contacted Weglot also but they do not have a clue yet.
I hope you have an idea where to look.
A Rankmath fan.
