bobheck11 2019-05-06 15:41 reporter ~0062032	Same error is occurring on mantisbt.org when I tried to add attachment. The attachment takes, but the error shows every time.

atrol 2019-05-06 16:15 developer ~0062033	I am not able to reproduce. Which browser do you use ? Are you able to reproduce using a browser without any installed plugin / add-on ?

bobheck11 2019-05-06 17:43 reporter ~0062034	atrol, Thank you so much for the quick response. It was indeed a Chrome extension that was causing the error. To be specific, it was the Moesif Origin & CORS Changer extension for Chrome. Again, thank you for the quick answer, and much thanks for creating such a wonderful tool. Please close this issue.
