?v=xxxxxxxxxxxx added to all urls

Maybe something to do with the Permalinks settings?

I checked the permalinks settings first thing when it started happening, but everything looks like normal. went back and double checked now, and updated them either way because I’ve read that sometimes it helps. but no luck.

for a while i thought that maybe it was some setting on a server level, and not on the wordpress install, but now I see that it’s only in the frontend the string gets added, not in the backend, so it’s clearly not a server/host issue. it’s gotta be a setting or rouge plugin somewhere…..

I found the cause! it’s because of geolocationing while using woocommerce

I had the exact same issue and it drove me insane trying to figure it out. I even restored my database and recreated the wp-content folder. I read this post and changed the geo location setting to not cache pages and it fixed the issue.
