So I’ve attempted reinstalling, deleting ELS subdirectory from AppData, changing my password, reinstalling Warcraft Logs Uploader and restarting my computer many times, yet I still get this error.
Any other suggestions on how to fix the issue?
Log out of the Web site. Go to the login page. Click Forgot Password. Pick a new one that is at least six characters long.
I have done this step multiple times, and I did it again after you suggested so. I am still unable to log into my Warcraft Logs Uploader client.
