What could drive DokuWiki to repeatedly replace the text of an internal link by one of another internal link?
Today I had to battle with DokuWiki, which kept replacing the text of an internal link. One specific internal link on one specific page. Adding the same link on another page worked fine. But as soon as I had edited and saved that specific page, the other link would be there again.
I tried opening the page with different browsers on different computers - always the wrong contents and the same useless editing. So not a browser cache issue, I guess. I cleared the browser cache nevertheless. I also opened the page with ?purge=true
appended to the URL to clear DokuWiki's cache - no effect.
The text file for the page had the correct contents, but its modification time wasn't changed by edit & save in DokuWiki.
For now, I "solved" my problem by renaming the page and using the new link text. But I would like to understand what is going on and how I could really solve this.
Clues for possible causes: I cheated by opening an editor by modifying the URL of the currently openend editor (i.e. something like https://modified_url?do=edit) and I used Rename Page (from the Move plugin). But I can't exactly tell which of these things I did to which of the pages involved.
Any ideas?
