Net prestashop 9.0.1 geinstalleerd, php 8.4.14 is actief. Frontend werkt, backend geeft ONMIDDELIJK error 500. Na wat zoeken kwam ik terecht op https://prestashop.com/blog/tech-en/what-is-the-http-500-error-and-how-can-i-fix-it-in-my-prestashop-online-store/
het aanpassen van regel 36 define('_PS_MODE_DEV_', false); naar define('_PS_MODE_DEV_', true);
zorgt ervoor dat de backend operationeel is.
Wat loopt hier fout en hoe los ik het op? Die dev mode moet volgens mij niet aan staan, en al helemaal niet na een verse installatie.
Als ik in de backend daarna via geavanceerde instellingen debug-modus deactiveer, veranderd die php file waarde terug naar "false" maar de shop staat nog steeds bovenaan in de zwarte balk in debug modus. Der klopt iets niet
