I recently had to install another database program known as "horde" and restart the server. Now, as a result, I can't get ERP5 back up because Zope doesn't start. Apache, SlapOS, apt, and everything else are up to date and check out. Here's Try 10 of the startup log I get:

I've looked up ways to start Zope manually, but I can't find anything that matches how it was installed for ERP5 using the ERP5-standalone installation script.

Computer: Dell PowerEdge T440 running a Xeon Silver Processor
Operating System: Linux erp 4.19.0-9-amd64 #1 SMP Debian 4.19.118-2 (2020-04-29) x86_64 GNU/Linux    (AKA Debian 10)

I'm not sure how to move forward. I would prefer not needing to reinstall ERP5. Anyone know what problem is?
