Hi Elie,
Enabling the SSL accelerator again is not hard, you just need to use the "WAE(config)# accelerator ssl enable" command, but, it's important to understand how this accelerator got disabled.
It's possible that it got disabled manually by mistake by someone around you, in which case, there is nothing to worry about, however, it's also possible that the accelerator was automatically disabled in response to a failure. If that is the case, I would recommend opening a TAC case to investigate it deeper.
The syslog should give you some hints on whether the SSL AO was manually or automatically disabled.
Regards
Daniel
