Internal server error on article

[siddadel]

1. An internal server error shows up when I try to access the following article on wagtail - ‘Even in the heat, there is some guilt if I drink the water…’. Below is a screen shot of the same.

2. The live version on the website opens without any error message.

3. The old version of this article accessible through revisions is editable. The revision on current version is not. Screen shot below.

Please, let me know why this happens :)

Try deleting all those extra "amp;"s in the Youtube URL.

Seems to be a bug in Wagtail where the '&' in& gets escaped and generates extra amp;s while saving. Interestingly, this becomes a problem when an article is saved many times (in other words, many revisions) thereby causing the string length to increase and overshoot db column capacity.
