Well I really don’t think I did it, but the response from my host (LightningBase…they are phenomenal, just like GP) says:
The .htaccess file for this site was missing the default .htaccess rewrite rule code:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
We inserted that at the bottom of the file, beneath the WP Rocket section, and the internal pages came back up. Let us know if you see any further trouble!
Thanks,
