Copy link

The "compare" function of page history tab breaks for page types that have the WidgetPageExtension applied.

Tested with a new install of

"cwp/cwp-recipe-cms": "^2.3",
"silverstripe/recipe-blog": "^1.3"

This results in the error:

ERROR [Emergency]: Uncaught InvalidArgumentException: $content parameter needs to be a string or array
IN GET /admin/historyviewer/schema/compareForm/6?RecordVersionFrom=3&RecordVersionTo=5&RecordClass=SilverStripe\Blog\Model\Blog&RecordID=6
Line 170 in /Users/matt/src/ms/silverstripe-example/vendor/silverstripe/framework/src/View/Parsers/Diff.php
