Your log-in attempt did not

Hi at all,

I don’t know if it depends on the module or the omeka-s platform, but when you try to view the image with the module this window appears with this writing: “Your log-in attempt did not appear to be successful. Please try again.” Without showing the image, if I click on the OK button the form loops. How can solve this problem? Thanks in advance.
Ciao Angelo
P.S. The module is Universal Viewer ver. 3.6.9
