GUI Blank page

Today the GUI of my FreePBX install stop working

got this error:

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

I try: amportal restart and got this ( amportal chown = same error)

Please wait…

**** WARNING: ERROR IN CONFIGURATION ****
astrundir in ‘/etc/asterisk’ is set to but the directory
does not exists. Attempting to create it with: 'mkdir -p ’

mkdir: opérande manquant
Saisissez « mkdir --help » pour plus d’informations.
**** ERROR: COULD NOT CREATE ****
Attempt to execute 'mkdir -p ’ failed with an exit code of 1
You must create this directory and the try again.

No issue with the call but that a problem for the administration!

Got the problem resolved by myself,
freepbx.conf as been corrupted
