After updating to v4.7.18 Beta 2 I get the following error: Error: Class "RedisException" not found (0) I'm not using Redis and don't have Redis configured in Advanced Configuration in my admin panel. How can I get my community back up?

This looks to be a known issue with the beta. You might want to restore from backup. 

If you havent restored already, we will have a new beta out very shortly which you can overwrite with and run the upgrader for

4.7.18 Beta 3 is now available, please upgrade to address this issue.

Thank you, the upgrade did the trick. I appreciate the support.

You will want to download the files and then upload them to your server, overwriting what is there. Once the upload is processed, go to {baseurl}/admin/upgrade in your browser and finish the process.

Typically, the issue for this to happen is a permissions issue on the server. If you are unsure how to resolve this, please contact your hosting provider.

Thanks Jim, I'll contact my hosting provider and see what they say, thanks again Kenny
