Just wondering if anyone else is having this issue. I am unable to edit or add camera URLs under Setup. Clicking save simply does nothing; even checking boxes under Camera section does not save. I can go to other sections under Setup. In fact, I cannot edit things under the General section either. I can go to Network section and make changes there. When there, clicking the save button clearly does save as the screen reloads. But when on General and/or Camera sections, clicking Save does not behave this way; simply does nothing. I am on 4.2.18.5, running on a Windows server. I downgraded to 4.2.18.3 and had the same issue. I'd love to review the logs, but they are empty. I do have logging enable under General Section.
