Open a post, then touch the three dots at the top to open the menu, then go to sort and select the one you want.

For some reason, lemmy.world dont like the old one, but all the others work

After this, the part where he trespass and try to open the locked door without any authorization got even more creepier... :|

Just tried on some browsers in private/incognito mode and all worked when not logged in.

But then I logged in, and the problem appears again. After some testing, I found that the problem seems to be on the default comment sort.

When set to old (which was my default one) I have the error, but when using any of the other options (new, top, hot), the comments display correctly.

EDIT:

The same happens when using mlmym.org to visit the lemmy.world instance. When set the comment sort do old, I got the error. Changing to new, it works.

But using mlmym.org on others instances I tried, it always works even when using the old as default.

Same issue here, checking on devtools there's an error 500 on the main page load

Have you tried to go to login page, fill in with your email only and click on forget password? If this work, maybe there's also some issue not related with the password complexity

EDIT: (I mean, if you at least got the email verification)

I also had the same issue on my first login (the email was verified, btw). The login button just went spinning and nothing happens. Trying the login on Jerboa gave me invalid credentials (it wasn't a mistype, because I used a password manager).

The workaround I did was to do a password reset and use a simpler one (was 50+ chars with special chars on, then changed to 32 chars and no special chars).

Not sure if what fixed was the reset itself, or the new password.

After this, the login went smooth on both the website and the app.

EDIT: And when posting this, the post submit button also kept spinning (the more than 200+ chars issue). But trying in a new tab, the message was actually sent.

And some minute later, on the old tab the message was sent, but the OP post changed from the "improvements and issues" to "The inability to post multiple pictures is holding Lemmy back.", but the comments below mine where for the "improvements and issues", while the comment above where to the other thread.
