[TYPO3-english] updateLoginTimeStamp error in TYPO3 and fe_manager

[jeppe at donslund.net]

Hi

I get this error in my TYPO3 8.7.17 with fe_manager

Core: Exception handler (WEB): Uncaught TYPO3 Exception: Argument 1 
passed to 
TYPO3\CMS\Core\Authentication\AbstractUserAuthentication::updateLoginTimestamp() 
must be of the type integer, null given, called in 
/var/www/www.domain.dk/www/typo3/sysext/core/Classes/Authentication/AbstractUserAuthentication.php 
on line 903

I have no idea where to search for a solution.


Best regards
Jeppe
