You've probably noticed various errors while browsing the web. Unfortunately, there are quite a few of them. The 405 error may not be as well-known as the ever-popular 404, but it can be quite confusing. Especially when you try to open an important page and instead see a "Method Not Allowed 405" message.
Where does error 405 come from?
This error can be called a browser-server conflict. It occurs when the browser tries to open a page in a specific way, but the server refuses to do so . Technically, HTTP 405 occurs when the access method used by the browser is not accepted by the server.
The problem often occurs when attempting to submit a form on a website . The browser may be using the GET method to submit data, while the server is configured to only accept the POST method.
Error 405 also often appears after server updates. Administrators change security settings, which can block certain access methods . This error can cause significant disruptions, especially on e-commerce sites or login panels.

405 errors can also be caused by outdated browser plugins . Old plugins may be attempting to communicate with the server in a way that's no longer supported. The same applies to old bookmarks – if you saved a page without HTTPS and the server requires a secure connection, you'll see a Method Not Allowed 404 message.
Sometimes , misconfigured redirects on a website are also the culprit . For example, if the old site used different access methods than the new one and the redirects weren't updated accordingly. In such cases, the 405 HTTP error may appear only on certain pages.
How to fix error 405?
Fortunately, there are several ways to deal with the 405 HTTP error. It's best to start with the simplest solutions.
- In Chrome just press Ctrl + Shift + Delete, select "cookies and other site data" and "cached images and files", and then click "clear data".
- In Firefox The process is similar – go to the menu, select "Preferences," then "Privacy and Security," and clear your data. This reset is often enough to get the site working properly again.
What if simple methods don't work?
If clearing cookies doesn't help, double-check the website address. Instead of entering it manually, it's better to copy it directly from the home page. Pay attention to the "https://" – some servers require this security feature and reject connections via the regular "http://."
It's also worth taking a closer look at the browser itself . In Chrome, go to the menu, select "Help," and then "About Google Chrome" to check if you have the latest version. Firefox has a similar option in the menu under "Help." Older browser versions may use outdated protocols that servers reject.
405 not allowed – solutions for webmasters
If you manage a website, check your .htaccess file – sometimes it's enough to add a line:
Header set Access-Control-Allow-Methods "GET, POST, OPTIONS"
This will allow the server to accept basic HTTP methods.
It's also worth reviewing server logs – they'll provide detailed information about which HTTP methods are being rejected. Based on this information, you can configure your security settings accordingly.
405 not allowed – solutions for developers
For developers, it can be important to check API code. A 405 error often occurs when endpoints are incorrectly configured. Ensure that the methods defined in the code match those used by the front-end.
For redirects, you need to verify that all paths are updated correctly, especially after migrating to HTTPS or changing the site structure.
405 error and positioning
A 405 error can also significantly damage a website's SEO on several levels. Google treats such errors as a warning sign – after all, a good website should function flawlessly. Let's see how exactly this affects SEO:
First, a 405 HTTP error makes it difficult for Google's crawlers to properly crawl the page . The bot attempts to access the content using the GET method, and if it encounters resistance, it may abandon the index. As a result, important pages or new articles may not make it into the Google index.
Additionally, the 405 Method Not Allowed error ruins the user experience. When users can't use the contact form or place an order, they quickly leave the site. Google notices this behavior – high bounce rates and low time on page are further red flags for the algorithm.
Worse still, a 405 error can also impact the crawl budget. This is the time limit Google allocates to crawling a website. If bots waste time trying to access blocked subpages, they may not have time to analyze new or updated content. It's also important to remember internal links. When they lead to subpages with an HTTP 405, they lose their SEO power . It's like building a bridge that doesn't reach the other side of a river – a waste of time and resources. That's why it's so important to regularly check your website with tools like Google Search Console , which allows you to spot indexing issues before they impact your search results.
When to call a specialist?
Sometimes the 405 Method Not Allowed error is too complex to resolve on your own, especially if the problem is server-side. In such cases, it's worth contacting your hosting administrator or developer. They have access to your server settings and can check for any configuration conflicts.
How to prevent 405 errors?
The best method is regular website maintenance, so it is worth:
- update the system and plugins;
- make backups before every major change;
- check server logs regularly;
- test the site after each update.
A 405 error may seem scary, but it's usually fixable without major problems. Often, updating your browser or clearing its cache is enough. In more difficult cases, you may need expert help, especially if the problem is server-side. The most important thing is not to panic when you see a "405 Method Not Allowed" error . It's worth starting with simple solutions—clearing cookies and checking the website address . If that doesn't help, you'll need to resort to more advanced methods or contact your administrator.
Let's also remember that prevention is better than cure. Regular updates and maintenance of the technical aspects of the website are essential. This will not only help us avoid 405 http errors but also other problems that could harm our website and its ranking in Google.
Finally, it's worth noting that every mistake is a lesson learned. The better we understand how our website works and what problems can arise, the better we'll be at handling similar situations in the future.
