[Koha-devel] Immediate logout in Koha 21.05.02 (03?)

[Michael Kuhn]

Hi

As written on this list on 26 August I tried to install Koha 21.05.03 
but after the installation Koha said the installed version was 
"21.05.02.003". Jonathan Druart wrote this comes from

  commit 8ea80995c590dad86c43df636456640d3aa84bab
      Increment version for 21.05.03 release

  -$VERSION = "21.05.02.002";
  +$VERSION = "21.05.02.003";

Today I updated a Koha 18.11.05 database into this Koha 21.05.02.003 
installation. After restarting memcached I executed "sudo 
koha-upgrade-schema instancename" - the output looked OK and ended with 
the following lines:

  Upgrade to 21.05.02.000 done [12:15:20]: Koha 21.05.02 release
  Upgrade to 21.05.02.001 done [12:15:20]: Bug 28567 - Set to NULL empty 
branches fields
  Upgrade to 21.05.02.002 done [12:15:20]: Bug 28813 - Update 
delivery_note to failure_code in message_queue
  Upgrade to 21.05.02.003 done [12:15:20]: Bug 28872 - Update syspref 
values from on and off to 1 and 0

It seems even if I installed Koha 21.05.03 it only upgraded to Koha 
21.05.02.

I don't know if there is any connection but whatever, I was able to open 
the staff client and to login - but as soon as I click on any link I'm 
logged out immediately. I am able to login again and then advance to the 
next link but then I'm logged out again etc ad infinitum. It is not 
possible to change any system preference (internal server error) or 
search for any users.

File "plack-error.log" sometimes tells me, without a timestamp:

  new(): failed: query object HASH(0x555f47cfad30) does not support 
cookie() and param() methods: Can't call method "cookie" on unblessed 
reference at /usr/share/perl5/CGI/Session.pm line 707.

File "plack-intranet-error.log" says:

  [2021/09/02 13:33:36] [WARN] Odd number of elements in anonymous hash 
at /usr/share/koha/intranet/cgi-bin/catalogue/search.pl line 577.

Can anyone please give me a hint how to solve this problem?

Best wishes: Michael
