full_user isn't finding any matching regex in the webpage HTML. The regex might have to change. I assume it's trying to get the title of the webpage?

youtube-dl/youtube_dl/extractor/dailymotion.py

Lines 484 to 486 in 695720e

	full_user = unescapeHTML(self._html_search_regex(
	r'<a class="nav-image" title="([^"]+)" href="/%s">' % re.escape(user),
	webpage, 'user'))

The playlist HTML scraper doesn't seem to find any video URLs on the user's videos page. Maybe dailymotion's HTML has changed?

youtube-dl/youtube_dl/extractor/dailymotion.py

Line 469 in 695720e

for video_id in re.findall(r'data-xid="(.+?)"', webpage):

^This for loop isn't finding any videos.

Then the dailymotion plugin must be broken then.
As I said. The command above was working properly, and finding/downloading the videos matching the regex a month ago. Sadly it is no longer the case.
I tried with the latest youtube-dl version (2019.07.02) and the situation remains the same.

Even though thats rather obvious, but it still didn't change.
