I met same problem. I first increase to 2045 and it worked fine only for a few days. Moreover I could not use model templates too. Now settings are 5000 for both vars. It’s fine. Hoping it would work for long time. Btw, I cannot save any settings with various SEO plugins (All in One, Meta SEO, High Performance SEO……). I tought it was same issue but in fact not. Still looking for solution.
