Hello,I've a copy of my website (http://www.ieraora.com/demophoto/) in a cloud IDE for test (CLOUD9).
Homepage is correct in both spaces, instead the page https://www.ieraora.com/demophoto/subgallerie?gid=2 in CLOUD9 refer error in subject.
Can You help me?

Hi ieraora,
​
It looks as if the error is coming from Line 263 of the page HTML for the form. Can you check the Code tab and see what is there?
