I have content editor web part in which I am using iframe to display data from some other site.
The iframe code is pretty simple such as:
Problem is sometimes SharePoint will remove the "src" from iframe. I noticed that it only happens when I try to Edit that page to make some other changes and then save it. So during loading of page when it is in Edit or Save mode it removes the "src" from iframe. And that too doesn't happen all the time but only sometimes. So the resulting iframe looks like this:
Why is that?
