Errore after editing

Hi, I’m Salvatore and I have a problem.
While I was working on Sheduler Manager (I was editing a field), the component gave me this error and I don’t know how resolve it.

There was error during configuration saving. Last stable configuration restored.
Error report saved to “com_scheduler_log.xml”

Someone could help me, please?

I’m use this component with Joomla 2.5

I’m waiting for your helping. Thanks.

You can check com_scheduler_log.xml, it will contains some details about the error.
If error reason is still not clear - you can share the log file here.

Ok, thank you very much.
