Works on Dev Machine, Not on Shared Server

After pressing the “Generate” button, nothing seems to be happening.
PHP 7.4 on a Dreamhost shared server
WP 6.0
SimplyStatic 2.1.5.8

The same version of the plugin works great on my dev machine at home. I wonder if the process is timing out on the Dreamhost server. There is no way to know, as there is no info in the UI and there doesn’t seem to be any log. Everything looks good on the Diagnostics page.

I ssh’d to the server and looked in the plugin’s static-files directory, which is where I believe the temp files should be written. It is empty.

I also tried enabling Debug Mode, and there is no debug.txt file getting created in the plugin’s directory.

I am trying to get a look at the wp_simply_static_pages table in the database, but right now phpMyAdmin is timing out on Dreamhost. If that gets fixed, I’ll post an update.
