I know this sounds complicated, but here is one way:
- Click "History" in the upper left corner of the page.
- Click on the version you want to return to. This will display the page in this version.
- At the bottom of the page, under "Download in other formats," click "Plain Text." This will download the source code for the desired version.
- Edit the page, delete all the content and paste the source you downloaded.
Admittedly, this can be made a little easier. Be sure to submit a ticket to the Trac website to request this improvement (a quick search didn’t work).
Of course, if the version you want to return is the previous one, you can also simply delete the current version. For this you need WIKI_DELETE .
