[Koha] Update from version 20 to 21 - cannot edit patrons anymore

[Isabel Pineda]

Hi.

I have just updated Koha to version 21.05 and now I am having a problem because I cannot edit patrons anymore. It seems that a javascript is missing?

The log file intranet-error.log gives this output:
File not found : default/js/locale_data.js at /usr/share/koha/lib/Koha/Template/Plugin/Asset.pm line 84.: /usr/share/koha/intranet/cgi-bin/members/memberentry.pl

Does anybody know how to fix this? I am running Koha on Ubuntu 18.04.

Thank you very much
