Invalid User Name and/or Password

hello

When this happened in the summer I reverted back to 3.44, starting this past week 3.44 also started to get the same error. 

So I upgraded to 3.49 skipping the earlier version that started the error originally.

Not sure how one determines if they need to upgrade to the newer version but in my case I was trying to fix the authorization issue.

I am not really sure that telling me not to upgrade is a good solution to my issue but thank you anyway for your response.
