I'm afraid that without any further information, we will not be able to comment on the particular reason that you cannot create a label template. Have you read through the documentation on how to do this? It can be found here: https://koha-community.org/manual/18.05/en/html/tools.html#label-templates-label Also, you may want to read up on how to construct a through bug report. This information may be found here: https://wiki.koha-community.org/wiki/Bug_Reporting_Guidelines
I read it all. Only when I click Save, I do not add anything.
All other profiles are added without problems, and Label Template is not added or edited.
Created attachment 82679 [details] I enter values I enter values and get a blank page. Help me please!
What is your exact Koha version? (see About page) What is your MySQL version? (also see About) Can you please check that the problem also appears using the English templates? (Ruling out an issue with the translation)
18.11.01.000 - Koha. 10.3.11- MariaDB. The problem also exists when using English.
I solve this problem not from the administrator interface, but by entering data directly into the MySql table.
I've tested both the label creator and the patron card creator and both work ok for me. I think it could help if you checked the error logs for an error. If you are using Plack, something should be visible in the plack-error.log when you save.
Are there any further updates here/the log details requested by Katrin for example? If not, shall we close this one out as 'RESOLVED WORKSFORME'
