When creating a new child and opening guarantor_search.pl to search and choose the guarantor, the page don't show the guarantor neither by typing the surname nor with 'Browse by last name:'.
The error seems to be linked to dataTables.buttons.min.js
It works for me, please confirm that you have correctly cleaned your cache.
Hm, it's broken for me too. I added a new 'Kid' patron, set to patron opened the pop up, all looks normal. But no search term will give me a result, same for browsing alphabetic register. I tried refreshing my cache.
strange, for me too, of course I have cleaned my cache, but Julian from Biblibre on my ask try also, and for him it was ok.
I'll try to change my BDD and find where is the issue.
Check the JS console and the Koha logs
One of those annoying bugs... that don't happen to everyone.
I think this is Bug 15916.
Looks like it has been fixed by bug 15916, please reopen if I am wrong.
