Meta community to discuss anything about the yiffit.net instance.
pawb was having an issue related to logins where the cookie was not set correctly. https://yiffit.net/post/13488055
The lemmy front end is almost exclusively javascript making api calls. I tested just now and it worked for me.
If its a related issue, some additional info and debug steps https://yiffit.net/post/12321196 (you can say hi to my alter ego).
Some quick things to try, private window to ensure no login data sneaked by the clear. Create a fresh profile with no plugins to test.
You know I think I had this before when they updated to 0.19 originally, too. Now I'm wondering if I just forgot to tick the box for clearing cookies when I did all that...
Edit: No; I did clear cookies. Hm.
Another dumb thing. If you're using a password manager, are the username and password correct/updated?
Are there any other popups that come at the same/similar time?
The only place I can find the error text "incorrect_login" is in lemmy-js-client-main. I'll have to do a bit more digging to find what all the causes are. At least one cause is bad username password combo.
Though, consistent errors on lots of pages makes me think some extension might be interfering with the javascript.
