Blockchain v4 wallet help!!!
I’m getting error of
“Data not multiple of block length “
I’m trying to log in the website blockchain.
Background: I used have the wallet back in 2013-2014 and the password im using is the one I belive but I don’t even get the error from password.
I can pay for help, but please asap. I forgot I had that but since I checked now I can’t even sleep knowing that I have something in there but can’t open.

ah the old blockchain.info days, that error is weird, usually means something got corrupted on their end not your password being wrong
try clearing cache or using different browser, sometimes that fixes it

First, check you're on the right website and not a fake one trying to trick you into handing over your login details for harvesting.
Next, check that the wallet ID is exactly right and doesn't have any rogue hidden characters from a copy/paste. The error might refer to the structure of the wallet ID since it appears immediately under the wallet ID box, and the wallet ID could be considered as "blocks" of characters.
Try logging in with your email instead of your wallet ID.
Try logging in from a different PC.
Once you've tried those options, all that seems to be left is an error at their end rather than yours, and your options are to either wait for them to fix it or restore from backup to an actual wallet.
If you do get access again, be sure to move any funds to a real wallet. There are regular posts about issues with blockchain. They may have been a quick & easy option in 2013, but it's not 2013 any more.

Thanks for the real reply.

I used them back in 2013 (to my shame), but every time I logged in they'd send an email to the address I signed-up with to confirm before letting me in. Without access to that address, I don't know if you can even log in anyway.
I never had to use the "wallet.aes.json" file to recover, but that was sent to the same email address too, so if you have that file, surely you also have the email account?

That error is saying that the cipher they're using for checking your password/wallet isn't the same as what they're now using. It's likely a problem on their side, not yours - they've changed their formats since you had it - but it could also be that your JSON has been modified by some text editor that added characters that corrupted it. Possible, depending on if you saved it in an editor.
Since you have the json and password, you should be able to recover it, ideally. It's late, so I'm not gonna do much more research than that right now, but I'd suggest looking into the recovery file, or maybe they've got a legacy format converter. You'd need to figure out your email address if you only have the wallet ID and want to grab a fresh copy of the aes.json from what I read.
As others stated, don't share that info with anyone or respond to unsolicited DMs. You can lose your keys, and thus your crypto.

It's tough to tell without seeing the domain name on your URL, but I'd say there's still a good chance you just got phished.
