Wordpress Migration .HTACCESS index.php Error

[Psyringe]

Migrating my Wordpress Multisite from a BlueHost CPanel environment.

Everything appears to be functional with exception of the Wordpress itself as non-functional with a cloned .HTACCESS. The plugins are functional, performing a redirect to a static website.

Have isolated the error to; RewriteRule . index.php [L]

While enabled the site throws an Error 500, but not much information in the logs screened so far.

While disabled the site throws an Error 404.

Search results have become scattered relations.
Where do I start on a fix?

This issue is remarkably similar to; .htaccess with RewriteRule

However my .htaccess has the Rewrite Rule; RewriteEngine on

Have tried the suggested fix with no change in outcome.

Swinging back through to say this is a PHP Version Error.

Previous hosting provider (BlueHost) was very deceptive with how they handled the platform (numerous recorded interactions). While running the version the former provider claimed, dialing this to an earlier PHP revision resolved the issue.

To anyone with similar issues; BlueHost had many puppet files outside the control of the user and no doubt anyone migrating from similar platforms might find issues caused by custom changes by a hosting provider.

There’s a likely fix to my .htaccess issue, but outside the scope of this forum.

Thanks for your eyes on the topic and for developing a very tight platform.
