Upgrade failed. Error #0003. Invalid username or license key. Please try again

Trying to update version on Wordpress. Keep getting this error. Copy/pasting directly from my S2 member account.

Hi TechBear.

Thanks for reporting it. I’ll look into it.

You can update manually if the updater isn’t working for you. Just download the zip file from your Account page and use your site’s plugin manager (WP Admin > Plugins > Add New > Upload) or via FTP.


I reviewed the site and found something that could have been affecting the update credentials validation. I think I sorted it out and my test upgrade worked fine. Could you please try it again?
