I’ve noticed that whenever I’m working in any kind of code editor (JS/CSS style editor, Raw Content Editor, Query String Editor), I often am unable to “Save”…
When visiting the site I then get a 429 error, for too many requests being sent at once.
The solution is to wait up to 5 minutes for the site to “cool down”, then retry saving, which usually works at that point.
This doesn’t always happen, but 10-15 times throughout my day I’ll be sitting, waiting for the site to not be so overloaded. I’m on a very high bandwidth plan through EasyWP for all my websites, so I don’t believe it has anything to do with my hosting.
