Hi,

I have had this problem for a week or two. When trying to check AdobeStock login settings at the Sites settings menu, Stock submitter shows a data check error: Page parse error. (Unknown Nightmare authentication error #2). Before Stock submitter showing the error message, the AdobeStock login window seems to accept the password, after that the photo captcha window is shown for some seconds and then closed.

Version v1.5.0.691

I didn't have a chance to try until now. Did not change any captcha settings but all seems to be working fine now. Thanks.
