I'm having the same issue.
Disabling passman removes the error.
Maybe it's not yet fixed

borekon picture borekon on 28 Feb 2018

But it is a bug in Passman. I open a Issue and PR which fixed it, but its not merged till now

tacruc picture tacruc on 28 Feb 2018

News about the merge ?
I ask just because it's filling my logs too :)

I am getting deluged with this log entry as well. Is it posible that this is a problem with the web-extension instead of the server side module? There is some weirdness with the extension right now that I opened an issue for on the web-extension, but got the 'its must be a browser issue' response. Based on what I am seeing, I think it is more than that....

Anyway, it would be good to see some action on this.

Has this fix been merged yet? I've been getting this error for a year or so thought i'd check it out because its starting to get annoying this error filling up my log - I am on the latest stable version of nextcloud (13 I think).

No the https://github.com/nextcloud/passman/pull/415 got closed.

tacruc picture tacruc on 14 Sep 2018

https://github.com/nextcloud/passman/blob/master/personal.php is fixed but there is no release yet. Please keep this discussion in https://github.com/nextcloud/passman :+1:

So, the bottom line is that the file located at:
../nextcloud/apps/passman/personal.php
needs to be changed.

Mine looked as follows:
\

Which I changed to:
\

Nothing more. I fail to see why this could not have been stated clearly somewhere by the maintainers, who apparently fixed the issue, but did not merge nor propagate it. At any rate, I made this change and my log is no longer filling up with this idiotic message. Hope this helps someone out there...
