How to remove the text seen in the bottom of the wiki (Check the bottom part of the image). This usually happens when I open a wiki in the tiddloid app for android. I dont know what triggers this. But I have seen this many times. This is seen when I scroll to the bottom of the wiki.
Looks like some javascript leaking out. Check any edited system tiddlers or additional javascript you have added. Consider searching for parts of the text you see in the wiki.
