De meest voorkomende zijn de 500 interne serverfout, de 403-fout (toegang geweigerd) en de 404-fout (pagina niet gevonden). Voor elk van deze fouten zijn er typische oorzaken en oplossingen. Deze handleiding helpt je om ze op een rustige manier op te lossen.<\/p>\n<h2>De 500 Internal Server Error<\/h2>\n<p>Een algemene serverfout, meestal veroorzaakt door een conflict tussen een plug-in en een thema, een beschadigd .htaccess-bestand of een te lage PHP-geheugenlimiet. Om dit te verhelpen:<\/p>\n<ul>\n<li>Schakel de plug-ins uit (hernoem de map \u2018plugins\u2019 als je geen toegang meer hebt) en schakel ze vervolgens \u00e9\u00e9n voor \u00e9\u00e9n weer in.<\/li>\n<li>Schakel over naar een standaardthema om het thema uit te sluiten.<\/li>\n<li>Genereer het .htaccess-bestand opnieuw door de permalinks opnieuw op te slaan.<\/li>\n<li>Verhoog de PHP-geheugenlimiet.<\/li>\n<li>Kijk in het foutenlogboek om de precieze oorzaak te achterhalen.<\/li>\n<\/ul>\n<h2>De 403 Forbidden-fout<\/h2>\n<p>Dit betekent dat de server de toegang weigert, vaak vanwege bestandsrechten, een beveiligingsplug-in of firewallregel, of een foutief .htaccess-bestand. Om dit op te lossen:<\/p>\n<ul>\n<li>Controleer de machtigingen voor bestanden en mappen (meestal 644 voor bestanden, 755 voor mappen).<\/li>\n<li>Controleer of er beveiligingsplug-ins zijn die de toegang mogelijk blokkeren.<\/li>\n<li>Hernoem het bestand .htaccess om te controleren of dit de oorzaak is, en sla de permalinks vervolgens opnieuw op.<\/li>\n<\/ul>\n<h2>De 404 Not Found-foutmelding<\/h2>\n<p>Een 404-foutmelding betekent dat de opgevraagde pagina niet kon worden gevonden. Als afzonderlijke berichten een 404-fout geven, maar de startpagina wel werkt, ligt het bijna altijd aan de permalinks. Om dit op te lossen:<\/p>\n<ul>\n<li>Ga naar <strong>Instellingen &gt; Permalinks<\/strong> en klik op \u2018Opslaan\u2019 om de regels te vernieuwen.<\/li>\n<li>Controleer of de pagina of het bericht daadwerkelijk bestaat en is gepubliceerd.<\/li>\n<li>Stel een omleiding in als de inhoud is verplaatst.<\/li>\n<\/ul>\n<h2>Controleer altijd het foutenlogboek<\/h2>\n<p>In het foutlogboek van je hosting wordt vaak het exacte bestand of de exacte plug-in genoemd die de oorzaak van een fout is, waardoor je niet meer hoeft te gissen en de fout snel kunt verhelpen. Controleer het logboek telkens wanneer er een fout optreedt.<\/p>\n<h2>Bij twijfel: maak een back-up terug<\/h2>\n<p>Als er direct na een wijziging een fout is opgetreden en je de oorzaak niet kunt achterhalen, is het terugzetten van een recente back-up de snelste manier om je website weer aan de praat te krijgen.<\/p>\n<h2>Hulp nodig?<\/h2>\n<p>Als een fout zich blijft voordoen, kan ons ondersteuningsteam de logbestanden controleren en je via de livechat helpen het probleem op te lossen.<\/p>","protected":false},"excerpt":{"rendered":"<p>Sooner or later you may hit a WordPress error.
