For some strange reason, despite not running any recent updates, our pagination links have broken on all categories.
So they are occuring as &p=2 rather than ?p=2. The link still works if you correct the url to a question mark, but for some reason, something is changing the links to include an & sign instead.
Updated all modules we can. We have Cloudflare and Nitropack in place as well, but using bypass on cloudflare and nothing changes.
We can temporarily fix the issue by invalidating indexers and reindexing then flush cache. But soon after it breaks again.
No errors in any logs including the cron log.
Any help would be great!
