Thank you very much. I disabled the cache plugin and the automatic update for Ninja Forms worked. I have reached out to Ninja and sent them the debug log.
I really appreciate you coaching me on how to research this. I’m a novice to WordPress and just trying to maintain our chorus website. I’ve now learned about WP_DEBUG and can perhaps even investigate some of the non-fatal messages I see in the log. 🙂
I’m marking this as resolved. Should I reply again to let you know what result I get from Ninja Forms?
This is from the debug.log:

[04-Nov-2025 16:00:34 UTC] Automatic theme updates complete.
[04-Nov-2025 16:00:34 UTC] Automatic updates complete.I do not have the premium version. I don’t know anything about php error logs. It appears from my first google search that I need to enable them to collect error logs. I will need to research this more.
thanks – Jon
