A lot goes into the seemingly simple process of navigating the modern internet environment, and sometimes, despite our best efforts, users are left disappointed. Every time these hopeful users access websites, clients and servers spring into action — or, at least, that is what’s supposed to happen.
Sometimes these connections fail for reasons that are difficult for both users and webmasters to discern. Thankfully, error codes are here to help diagnose and troubleshoot such issues. The HTTP error 403 code can be an especially frustrating one, as it denies users access to web pages. Having a large number of them on a site can then also erode trust in the brand.
Determined to avoid 403 errors? Below, we’ll describe in detail what these client-side errors mean, the possible causes behind them, and what users can do to clear out these errors.
The 403 HTTP status code, in its most basic form, means that a client does not have permission to access a particular web server or internet page. A 403 error represents an issue with the client and can occur regardless of whether the user is operating on Google Chrome, Firefox, Safari, or other web browsers. Thankfully, the problem that’s preventing the server from allowing access to a particular page is usually fixable.
There are several different reasons why a web browser may get an access denied message along with an HTTP 403 forbidden message. Often, the problem is simple: individual files are misconfigured. Server configuration files such as .htaccess could be infected with malware, prompting a variety of problems. Home page files could also be a culprit, as anything not named index.html or index.php could lead clients to a dead end.
Other 403 errors result from issues with file permissions. As clients attempt to access files, folders, or even entire directories, they could be turned away if the server doesn’t recognize the permissions being shown by the client. This is a common error in web hosting, as most users will be allowed to access files but not make any changes to them or save them on the server.
While 403 forbidden errors are technically caused by the client, as they do not have the proper permissions to access the file, there are some exceptions in which the website that's meant to be accessed is to blame. WordPress hosts in particular often see these errors pop up specifically for users attempting to access sites in which specific WordPress plugins are configured incorrectly.
There is also a chance that the wp-content folder in the main WordPress directory cannot be accessed by the host itself. In this case, faulty security plugins or settings are typically to blame.
Another common cause for an HTTP 403 forbidden error? An incorrect or outdated domain name. Double-check that the web address is correct and try again. If this fails, the host of the domain may have changed. Perhaps the host has even set up a new configuration of access permissions which may keep the client out.
While it’s often not particularly difficult to fix a 403 error once the culprit has been found, getting to that point may take a bit of time. That’s because there are so many different ways in which the 403 forbidden error could be triggered. Some of the best methods for troubleshooting and solving these errors on the client side include:
Keep in mind that it's entirely possible for site assets that are being accessed to be hotlinked. Hotlinking occurs when users display images on their websites but rely on the URL of the sites that actually host these image files. In this situation, the server simply will not allow access.
A helpful analogy: imagine charging admission to see a prized painting, and yet, would-be customers can easily view the artwork through a window outside the venue instead. For obvious reasons, many websites will block hotlinked images with an HTTP error 403 to keep unwanted web traffic away.
Business-oriented website owners or webmasters may come to notice that users are having issues with 403 forbidden errors. In this situation, a few simple steps can be taken to fix the problem or limit the damage:
It can take a lot of time and effort to deal with 403 errors alone. From tinkering with the control panel to reconfiguring folder permissions and often consulting online tutorials, it's easy to waste precious resources on a problem that cannot always be solved by novice webmasters. In some situations, the problem is beyond the control of the website owner.
Sometimes, none of the standard advice will play out favorably. Various internet service provider (ISP) settings or firewall protections could be responsible for the errors — and in these situations, there is little that ordinary web owners or webmasters can do to mitigate the problem. At some point, it may be prudent to contact the web hosting provider or server administrator to see if they can shed some light on the problem.
If you have noticed that your website is continually plagued by 403 and other types of error codes, it's time to take action. These codes are a bigger deal than they may seem — they prevent potential clients or customers from accessing your web content and may also damage your reputation. Unfortunately, you likely lack the time, experience, or knowledge needed to resolve these errors on your own.
