I have a web agency and I was changing 80 websites to contact form 7 and suddenly got this same error after doing 20 successfully. The way I fixed this was simply putting a different email address in the “to” section and it worked, then I changed it back and it worked again, cheers!

I can’t get updraft plus to work on any of my sites, I keep getting this error message when I test the FTP settings
FTP settings test result: Failure: we did not successfully log in with those credentials.
