The file edit is only necessary if you intend to use autosaving with Quick Reply.

In file clientscript/vbulletin_quick_reply.js:
FIND:
PHP Code:

vB_Editor[QR_EditorID].write_editor_contents("")

REPLACE WITH:
PHP Code:
// vB Drafts
// Old
// vB_Editor[QR_EditorID].write_editor_contents("")
// vB Drafts

However, in the installation instructions, you say the edit should be made if you want to use drafts with Quick Reply.

The code you say to replace is not in the clientscript/vbulletin_quick_reply.js file.
