Hello there, I have the same problem here. I wasn’t using All in one SEO pack which seemed to be the causing conflict in the previous case.
I was using the Add Meta Tags plugin (https://www.ads-software.com/extend/plugins/add-meta-tags/) + Facebook Open Graph Protocol but assuming the first could cause conflict too I deactivated it.
Result when trying to share on facebook:
- category page title is loading the title of the latest post in the category
- category description (which I setted in the wordpress category edit page) seems to be overwritten by site description (which I setted in the wp general settings page)
home page and single posts, instead, work just fine.
I am just a beginner and have near-to-none knowledge in programming and php, so I may have done something wrong, but can’t figure out what.
Thank you for any help!
