Additional context

No response

This is because of rate limits. They were moved from config file to database in Lemmy 0.17.0, so you need to manually increase "Message rate limit" and "Search rate limit" in lemmy-ui under /admin to a high number.

[Tealk]

we should still include in the readme, are there any suggestion values?
my settings are:

Message rate limit: 180
Search rate limit: 60

also, since the update to 0.2.1 it works again without changing the values

[Nutomic]

It works if you only make a few requests, but as soon as you reload the page a couple of times the error will show again.

For now I just set them to 9999. My idea for a proper fix was to test how many API requests a page view with lemmy-ui makes and then compare it to requests for lemmybb. Then increase the rate limits by that same factor. You could give that a try if you have time. And if that doesnt give an extremely high number, we could change the defaults in Lemmy so that manual changes arent necessary.

The error ksm with the 2.0 when first loading and now no longer no matter how many times I reload
