Hello! 

I just had 30+ sites go down, and I was hoping someone could give me a quick answer.

I had problems with caching in a module, so I went into the Host settings and turned off the cache, so see if that could solve the issue.
Now all my sites are getting this error. Any suggestions?

I am trying to go into the database to reset this parameter by hand, but I am not sure where it is stored...

Value cannot be null.
Parameter name: cachekeysArg
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I was able to resolve this.

In case someone else run into this --

I went into the database, and the dbo.hostsettings table. There I change the value for 'PerformanceSetting' to 3.


BTW - the only thing I did in the host settings was changing 'cache setting' from Moderate to None.
