Hidden page content in Edit mode

Question

We're testing a conversion of downloaded Confluence 3.5.7 to downloaded 5.5.2 (we want to go to OnDemand 5.5.2) , and when I click Edit on some of the 5.5.2 pages, all I get besides the page title is a blank, gray screen.  No text, task bar, error message, buttons...  This seems to occur for some - but not all - pages in certain areas of a Space.

Could this be a conversion error?

I tried to Answer my own Question on July 22 and Accept it, but apparently  that didn't work.  I'll try again now, but I see no button / link that will let me Accept this.

As a test, I copied the text from one of the 3.5.7 pages that could not be edited in 5.5.2 into a new 5.5.2 page, and that page could be edited.  This showed me that there was nothing wrong with the data on the page and nothing wrong with any Confluence settings.  What the problem is, I don't no - I still suspect it was an error during the conversion.

Hi Guilherme,

Thanks for responding.  I checked the Settings you suggested and everything seems OK.  There's only a very small percent of pages that display correctly but show nothing in Edit mode.  For one of these pages, I copied the text from the original 3.5.7 page and pasted it into a new 5.5.2 page.  It displayed correctly AND showed all text in Edit mode.   So I further suspect that it was a conversion problem somehow.
