Start with simple checks (status pages, logs, credentials), use diagnostic tools, and escalate to your host when the problem is on their side or beyond your access. Regular maintenance,updates, backups, monitoring,prevents a large portion of issues.<\/p>\n<p><\/p>\n<h2><span class=\"ez-toc-section\" id=\"FAQs\"><\/span>FAQs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><\/p>\n<p><strong>Q: My <a href=\"https:\/\/infinitydomainhosting.com\/kb\/what-is-website-down\/\">site is down<\/a> for some users but not others. What gives?<\/strong><br \/>A: Often this is <a href=\"https:\/\/hostadvice.com\/blog\/domains\/what-is-dns-propagation\/\" target=\"_blank\" rel=\"noopener\">dns propagation<\/a>, local <a href=\"https:\/\/www.a2hosting.com\/kb\/getting-started-guide\/internet-and-networking\/clearing-the-dns-cache-on-your-computer\/\" target=\"_blank\" rel=\"noopener\">dns cache<\/a>, or <a href=\"https:\/\/www.hostinger.com\/tutorials\/what-is-cdn\" target=\"_blank\" rel=\"noopener\">cdn<\/a> caching. Ask remote users to <a href=\"https:\/\/www.a2hosting.com\/kb\/getting-started-guide\/internet-and-networking\/clearing-the-dns-cache-on-your-computer\/\" target=\"_blank\" rel=\"noopener\">clear dns cache<\/a>, check with dig\/<a href=\"https:\/\/hostadvice.com\/blog\/domains\/what-is-nslookup\/\" target=\"_blank\" rel=\"noopener\">nslookup<\/a> from different locations, and verify CDN configuration.<\/p>\n<p><\/p>\n<p><strong>Q: How can I tell if it\u2019s my code or the server causing a 500 error?<\/strong><br \/>A: Check the server error logs for stack traces or messages. If logs show application exceptions, it&#8217;s likely code. If logs show resource limits or service crashes, the server is the cause.<\/p>\n<p><\/p>\n<p><strong>Q: Are automatic backups enough?<\/strong><br \/>A: Automated backups are great, but you must test restores periodically and keep copies off-site. Backups that aren\u2019t restorable are as bad as no backups.<\/p>\n<p><\/p>\n<p><strong>Q: My emails are going to spam,what quick steps help?<\/strong><br \/>A: Verify SPF, DKIM, and DMARC records, avoid sending from shared IPs with bad reputation, and consider using a reputable email service provider for transactional mail.<\/p>\n<p><\/p>\n<p><strong>Q: How often should I review server logs?<\/strong><br \/>A: For active sites, check logs daily or set up automated alerts for errors and unusual spikes. For smaller or low-traffic sites, weekly reviews plus alerts are usually enough.<\/p>\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Quick checklist before you start troubleshooting Before you dive in, do these quick checks: is the problem affecting everyone or just you?&hellip;<\/p>\n","protected":false},"author":1,"featured_media":50196,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"content-type":"","_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[1,4593,9,4594,87,3,5,10,4,11,7,88,8,2],"tags":[486,10629,811,415,683,10630,677,554,1032,2265,579,10611,78,1826,866,262],"class_list":["post-50195","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-general","category-databases","category-domains","category-networking","category-online-marketing","category-php-scripts","category-seo","category-servers","category-ssl-certificates","category-support","category-web-design","category-web-hosting","category-website-security","category-wordpress","tag-backups","tag-common-general-issues-in-hosting-and-fixes","tag-configuration","tag-database","tag-dns","tag-fixes","tag-hosting","tag-maintenance","tag-migration","tag-performance","tag-security","tag-server-issues","tag-ssl","tag-troubleshooting","tag-uptime","tag-web-hosting"],"_links":{"self":[{"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/posts\/50195","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/comments?post=50195"}],"version-history":[{"count":1,"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/posts\/50195\/revisions"}],"predecessor-version":[{"id":50197,"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/posts\/50195\/revisions\/50197"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/media\/50196"}],"wp:attachment":[{"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/media?parent=50195"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/categories?post=50195"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/infinitydomainhosting.com\/kb\/wp-json\/wp\/v2\/tags?post=50195"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
