php_intl extension not recognised SilverStripe

Question

I'm using MAMP to install SilverStripe and had to enable php_intl in the ini. After restarting MAMP multiple times, it still gives me this error:

ERROR [Emergency]: Uncaught Exception: This backend requires the php-intl extension IN POST /silverstripe/install.php Line 31 in C:\MAMP\htdocs\silverstripe\vendor\silverstripe\framework\src\i18n\Data\Intl\IntlLocales.php

I have checked all files that I could find and were related to it, but php_intl.dll is there and it's enabled in the ini.

Answer 1

The issue is resolved.

Due to a tunnel to another DB, the connection SilverStripe tried to make was interrupted and seen as invalid.
