Thread:Extension talk:TemplateData/Blank Pages

I'm having issues on my wiki where editing certain pages is returning a blank page response upon submit. I commented out the TemplateData.php line in my LocalSettings file and then editing started working properly. The page in question has a lot of templates in use, so perhaps that is part of the problem? Has anyone else experienced this? I looked on Phabricator, and didn't see anything that looked like this bug.
