There could be several reasons why a website is not opening properly or at all in the Safari web browser. In this article, we will explore some of the most common causes and solutions to troubleshoot and fix website loading issues in Safari.
HTTPS/SSL Certificate Issues
One of the most common reasons a website may fail to load in Safari is an invalid or expired HTTPS/SSL certificate. Safari strictly enforces HTTPS security, so any issues with your SSL certificate will prevent the site from loading.
This typically displays an error message in Safari such as “Safari can’t establish a secure connection to the server” or “This site’s certificate is not trusted.” The certificate may be expired, self-signed, or not issued by a trusted certificate authority.
To fix this, you will need to purchase and install a valid SSL certificate issued by a trusted CA on your web server. Some web hosting providers include a free basic SSL certificate, or you can purchase more validated certificates from providers like Comodo, DigiCert, or LetsEncrypt.
Be sure to install the certificate properly on the server and enable HTTPS traffic. You may need to adjust your site URL settings to use HTTPS instead of standard HTTP as well. Once the valid SSL certificate is installed and enabled, the website should load normally in Safari.
Outdated Safari Version
Another possibility is that you may be running an outdated version of the Safari browser that doesn’t support the web technologies used on your site.
Certain HTML5, CSS3, or JavaScript features may not be supported in older Safari versions, causing pages to display incorrectly or fail to load properly.
Try updating your Safari browser to the latest version and see if it resolves the loading issues. You can find the update in the App Store on MacOS.
On iOS, go to Settings > General > Software Update to update your Safari mobile browser.
If updating Safari does not help, you may need to adjust the code on your site to be compatible with the Safari version your visitors are using.
Problems with Web Hosting Configuration
Configurations on your web hosting account could also potentially disrupt site loading in Safari.
For example, if your hosting has mod_security or other firewall rules enabled, it may block legitimate Safari traffic and prevent pages from loading properly.
Contact your web host’s support team to check if any security rules or IP blocks are interfering with Safari access. They can whitelist Safari user agents or adjust firewall settings as needed.
Also ensure your web hosting service has TLS 1.2+ enabled, as Safari requires modern TLS protocols for secure HTTPS connections.
Incompatible Safari Web Content Blockers
Safari has the ability to install web content blocker extensions that can block ads, trackers, and other elements on websites.
However, some Safari web blocker extensions are overly aggressive and may break site functionality, preventing pages from loading correctly.
Try disabling any Safari content blocker extensions/apps you have installed one-by-one to see if one in particular is causing the loading problem.
You can enable/disable content blockers in Safari preferences under the Extensions tab.
Problems with Custom Code or Plugins
If you are using any custom code or plugins on your site, incompatibilities could potentially lead to loading issues in Safari.
For example, Safari may not support an older JavaScript library you have implemented, or a specific jQuery plugin may conflict and cause problems.
Try disabling plugins one-by-one to isolate potential conflicts. Check that any custom scripts comply with modern web standards supported in Safari.
Also update any outdated plugins or scripts to their latest available version, which may have fixed Safari bugs present in older releases.
Web Font Loading Issues
Safari can be particularly strict when it comes to the loading of web fonts from services like Google Fonts.
If you are using web fonts, try disabling them as a test to see if it resolves any loading problems in Safari.
Ensure any web font scripts are loading asynchronously and that you have the proper CORS Access-Control-Allow-Origin headers configured on your server.
You may need to optimize the way fonts are loaded for better compatibility with Safari’s standards.
Problems with Server-Side Code
On sites using server-side platforms like PHP, Ruby, or Node.js, incompatible code could also disrupt Safari site loading.
Make sure your server stack and site source code is fully compatible with Safari’s rendering engine.
For example, older PHP versions may need to be updated to fix bugs or add Safari support.
Review your back-end code to check for any syntax or logic errors that could prevent proper page loads in Safari.
Incorrect Apache .htaccess Rules
The .htaccess file is used to customize Apache server configurations. If you have incorrect .htaccess rules, it could block Safari access.
Examine your .htaccess file for any syntax errors or invalid rewrite conditions blocking Safari traffic.
Adjust the rules to allow and optimize loading for Safari user agents.
You may need to add exceptions for Safari browsers if you have rewritten site URLs or enabled other custom functionality.
Problems with Server Caching and Compression
Web server caching and compression systems can sometimes malfunction and serve incorrect or corrupted content to Safari browsers.
Try disabling server-side caching temporarily in a test environment to see if it resolves Safari page loading issues.
Check that gzip/deflate compression is functioning properly for Safari user agents. Misconfigured compression can break page loading.
If you are using a content delivery network (CDN), there could also be potential Safari compatibility issues with their caching servers.
DNS Lookup Issues
Safari relies on DNS services to lookup and route to the server IP hosting your site domain.
Very rarely, DNS issues could prevent Safari from locating your site server and loading pages.
Confirm your domain DNS records are configured correctly and propagating as expected.
Try temporarily switching to a different DNS provider as a test to see if it fixes loading problems.
You can also do a manual DNS lookup from the terminal to verify Safari can resolve your domain to the correct IP address.
Conflicts with Safari Developer Settings
If you have Safari Developer tools enabled, certain settings like Device Simulation could interfere with normal page loading.
Try resetting Safari developer options by clicking Develop > Disable Develop Menu in the Safari menu bar.
This will reset all developer settings that could potentially disrupt the typical Safari browsing experience.
Issues When Site is Open in Multiple Tabs
Uncommon bugs can sometimes occur when the same site is open in multiple Safari tabs simultaneously.
As a test, close all other Safari tabs with the site open. Then try reloading the site in a single tab only and see if loading works normally.
If the site only has issues when open in multiple tabs, it indicates a browser-specific bug that will require further troubleshooting.
Steps to Diagnose Loading Issues in Safari
Here are some general steps you can take to diagnose the potential cause when a site fails to load in Safari:
- Check Safari browser version and update if out of date
- Try a hard refresh (Shift + Refresh) or clear Safari cache
- Test site loading in Safari private/incognito window
- Disable Safari content blocker extensions/apps
- Launch Safari in Safe Mode to disable other extensions
- Reset Safari and delete browser history/data
- Try different network connections and locations
- Check server logs for Safari-specific errors
- Test site on different MacOS/iOS devices
Taking methodical troubleshooting steps can help narrow down the cause of loading problems in Safari.
