problem transferring your user data ...

Post by Nikolaus Hold » 08 Jan 2019 10:45

What is the reason if you can not log in and get the error message: There was a problem transferring your user data, so this action has been canceled for safety's sake to prevent you from misallocating your changes to another user. Please resubmit this form. See attatched hardcopy.

"resubmit" does not help at all. Is this perhaps due to a hacker attack?

The mechanism that prevents session hijacking on the MediaWiki software has false positives from time to time, which may be related to specific browser behaviour concerning security, especially when switching from a http connection to a https connection or vice versa. Please clear cookies, and try to login by forcing https or, alternatively, by forcing http:

- to force https: https://www.cpdl.org/wiki/index.php?tit ... :UserLogin

- to force http: http://www.cpdl.org/wiki/index.php?titl ... :UserLogin

This will (hopefully) clear any issues with previous http/https sessions.

By the way, I'm still investigating your problem with the automatic filling of file information while uploading scores. I have activated a specific log, and it is now clear that your system has a very specific behaviour concerning the interaction with the MediaWiki software. I guess that the two problems that you noticed can be related to such specific security settings or behaviour. I should investigate further.

No luck with your suggestions.

Since 9.1.2019 I was able to work undisturbed, but today I am locked out again: problem transferring your user data ...

I restarted Firefox and deleted all cookies and web page data. Then I tried your first link without success.
Afterwards restarted and deleted all cookies and page data again. The attempt with the 2nd link was just as unsuccessful.

Then I went back into the CPDL as originally, (after restart of Firefox and delete all cookies and web page data again) and tried a login starting from the page Moritz_Hauptmann. I was directed to
https://www.cpdl.org/wiki/index.php?tit ... +Hauptmann
The login attempt was then just as unsuccessful.

So once again I can only wait until tomorrow and hope that the blockade has passed by then.
