Builder returns server 500 on every page after host migration. Front end works fine.

Hi all, hoping someone has seen this one.

After migrating a site to GoDaddy cPanel hosting, the Bricks builder (?bricks=run) returns the host’s 500 Internal Server Error page on every page, including a brand-new blank page. The front end, previews, and WP admin all work normally. The builder worked for about a week after the migration, then started failing.

Ruled out so far:

  • All plugins disabled via Health Check troubleshooting mode: still 500
  • Fresh Bricks 2.4.5 uploaded, license active, no child theme
  • PHP 8.2 and 8.3 both fail
  • Nothing in WP debug.log or the Apache error log
  • No hosting resource-limit faults when it fails

Environment: WP 7.1.4, PHP 8.3, MariaDB 10.11, 512M memory, 300s execution time, max_input_vars 1000. Plugins include Automatic.css, ACF Pro, The Events Calendar, Code Snippets.

Has anyone seen the builder crash at the server level like this with nothing logged? Any ideas what to check next are appreciated. I’ve also opened a ticket with Bricks support.
