I have a function on the backend to create an account, but today it suddenly stopped working. Any solution???
It might just be routine maintenance happening so please keep a check on it to see if it works later on.
Otherwise, please post your code used for this along with any screenshots etc so that it can be checked.
Everything was working just fine, I even launched an app yesterday and some signed up for it, I have already received reports that they were unable to create the account, I went to test it and saw that it is not registering.
It can be a maintenance, I’ll wait, but it ends up being boring 
Fingers crossed it is just something simple like maintenance and not a bigger issue.
Please put a ticket in through Wix Support or call them directly so that they can pass this onto the relevant team if the Wix Admin/Mods in this forum are not aware yet.
