Problem: Whether enabling dual or single edit editing in Special:ManageWiki (screenshot #1| | screenshot #2), the following error is returned, when in Visual Editing mode, "Error loading data from server: apierror-visualeditor-docserver-http-error: (curl error: 52) Server returned nothing (no headers, no data). Would you like to retry?"
Reproducable? Yes, tested on theoriegnqc and reproduced on meta
What Should Happen: Whether using single- or dual-edit tabbed environment, VisualEditor should switch between the source and visual editing GUI environment seamlessly.
