I’m getting hundreds of broken links reports on links like these (xxx is typed by me): https://xxx.xxx/blog/page/2/\”https:\/\/pinterest.com\/pin\/create\/button\/?url=https:\/\/xxx.xxx\/blog\/&media=https:\/\/muchay.pt\/wp-content\/media\/2021\/05\/xxx.jpg&description=xxx”
It seems like an error created from the share buttons on the theme.
Overall, that would be true, but the theme has sharer.php which generates the links to share. It’s creating those links with that structure to share on social or email and those are creating 404 errors for some reason.
