We have seen following error in our log files: >Use of uninitialized value $plugin_version in string ne at /home/koha/Koha/Koha/Plugins/Base.pm line 81 I first thought that this happened because we had a plugin without a version number, but fixing that didn't help to get rid of this message. So I'm wondering could this be again a problem with using global variables to determine plugins version (variable our $VERSION) and plack? We've had problems with them before, see bug 38357. I'm unable to provide any plan to reproduce this since this happens randomly (which imo strongly point to plack). We are using version 24.05.01.
