Hello, @gblackett
Certainly, here’s a concise action plan:
Reset Permalinks: In WordPress settings, save the permalinks again to fix 404 errors.
Check File Permissions: Ensure wp-content/uploads has correct permissions.
Increase PHP Memory Limit: Add define(‘WP_MEMORY_LIMIT’, ‘256M’); to wp-config.php.
Restore .htaccess: If missing, recreate the .htaccess file with default WordPress rules.
Manual WordPress Update: If issues persist after an update, try updating WordPress manually.
I hope my solution is helpful to you!
Best Regards
