Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires smarty/smarty ^3, found smarty/smarty[v3.1.11, ..., v3.1.48] but these were not loaded, because they are affected by security advisories ("PKSA-5rsx-p2fk-h2gr", "PKSA-2q9d-8kh9-49wx", "PKSA-pght-23ww-rrdy", "PKSA-6y8p-nrf4-ysf5", "PKSA-yr6f-z9sx-cps3", "PKSA-28zg-9h7g-fhvp", "PKSA-m8bd-7wwg-qgrb", "PKSA-31hv-m6rg-8ryk", "PKSA-98zc-53yc-qt81", "PKSA-t4kv-1sv2-1mzx", "PKSA-wc9h-gs49-76tm", "PKSA-thph-wfk6-pp4j", "PKSA-hgp5-21g7-7phg"). Go to https://packagist.org/security-advisories/ to find advisory details. To ignore the advisories, add them to the audit "ignore" config. To turn the feature off entirely, you can set "block-insecure" to false in your "audit" config.
