Unable to change any directory on Library

Hello,
I have Serviio PRO v 1.10, and since the last release I can not change any directories in my library settings.
I can delete, add directories, but when I check the save button, there's an error message saying :
An unexpected error occured : (500) check the log

and here what i find in the log

WARN [ServiioStatusService] RuntimeException occurred. Returning error code 500 to the REST layer. Message: Cannot initialize searcher, the index is possibly corrupted.

  Code:
