Trouble adding and editing posts and products

I’ve been using OceanWP for a few years now, and I’ve never had this issue. When adding or editing a product or post, the title and name will automatically change to something else. It’s always the same thing: “Celtic Cross ~ 12 Rune Layout”. I don’t even know what that is… I’m assuming it’s something I posted on years ago? I don’t know. I’ll correct it, and it switches right back. The publish date also changes from 2020 to 2017. I thought they weren’t posting at all until I noticed the date changes. If I try to do a Quick Edit, the name changes, the slug changes, the publish date changes, AND a password is inserted…

To add a product, I have to upload it from a .csv file and then edit it, and continuously correct the name.

Ever hear of this before? Naturally, I tried deactivating each plugin individually to see if that would fix it, but no luck. I also had my domain host install a backup from a month ago, and that didn’t fix it, either.

I’m not a web developer. Far from it. Everything I’ve done is from researching and trial & error. Not a clue what to do from here…
