Panel creating broken txt files?

Hi everyone,

i recently purchased a kirby licence and installed kirby on my laptop. It’s running a linux and an apache webserver.
After some issues to create a new user (same username/password not allowed?) its seems working fine.

if i create a new page via the panel and click on safe, kirby creates the directory correctly but the .txt file doesn’t show the correct pattern.

i think it should looks like:

Title:
----
Year:
----
Tags:
----
Text:

how actually they look:

T: 


what’s my failure?

Thanks

Could you post your blueprint? I’ve seen this error before somewhere …

It seems that the mb_string extension for PHP is missing. This is a typica bug that happens because of the missing extension. Could you please check your phpinfo for mbstring?

shame on me. i didn’t install the php extension.
thank you …
