We recently notice that posts for both site languages are returning on search.
On this page for example, use “Daniela” as the name search and submit: https://peiwebsolutions.thedev.ca/stewartmckelvey2/our-team/
Both language posts are returning.
(Note in the search form “Language” refers to a tag on the post, not the language type for the post. The site’s primary language is English, other language is French).
It was caused by a recent change – which was to fix other polylang related issues, but there was a mistake there I just noticed. I made a correction on the plugin code on your site directly, it should be fine now.
I will make sure to include this fix in the upcoming release.
