Hi, I am still new with Sitefinity and still exploring, i am using sitefinity 5.1 I get this error while i try to edit one of my pages RegisterRequiresControlState can only be called before and during PreRender. i also posted some Print Screen below But i still can preview, edit title properties, and edit permission Any idea why this is occurring ?
I too am having this issue but in version 6.3.5000. It also occurs when I'm trying to edit a page and while I have no custom widgets, I do have multiple document lists on the page. What do I do to get around this obvious bug?
