See https://phabricator.wikimedia.org/T95839 and https://phabricator.wikimedia.org/T150373 for potential technical background information on the software bug itself.

Yes, I've seen these two pages for many times. But I still don't know how to fix it.

After updating from 1.26 to 1.30 on one of our many wikis we are now also experiencing this problem. Is there any "solution" ? I am quite sure this is related to the current config of php5 / apache2 / debian on our side but I do not know where to look!

I just noticed: when I disable the "LastUserLogin" extension this problem is gone.

The extension is unmaintained and it has several issues looking at its talk page. You probably should avoid using it.

I will talk to the programmer, I am sure we will update it...

Just for information, i had now the same issue, and it was solved disabling "LastUserLogin" extension

I had a similar issue in media wiki 1.34 when I try to change my password after logging in. Th error went away after disabling "LastUserLogin" extension.
