What is a 405 error?

Your browser talks to a server using methods. Two common ones are GET, which asks for a page, and POST, which sends data like a form. A 405 error means the server refuses the method you used. It is like pushing a door that says "pull".

Common causes are a security rule that blocks POST, a broken plugin, a wrong .htaccess file, or a wrong web address.

Warning: Take a backup before you change files. A backup is a saved copy of your site.

Step 1: Check the address

  1. Look at the address in your browser.
  2. Check that it uses https:// and the same version of your domain (with or without www) as your site settings.

Step 2: Turn off plugins

  3. Try the action again.

Pay special attention to security and form plugins.

Step 3: Reset .htaccess

The .htaccess file is a hidden settings file that controls how the server handles requests.

  1. Log in to your hosting control panel and open File Manager.
  2. Open your WordPress folder, often public_html.
  3. Turn on Show Hidden Files.
  4. Rename .htaccess to .htaccess-old.
  5. In WordPress, click Settings, then Permalinks, then Save Changes.

WordPress writes a fresh file.

Step 4: Check the theme

  1. Click Appearance, then Themes.
  2. Activate a default WordPress theme.
  3. Try your action again.

Step 5: Check the security firewall

A firewall is a guard that blocks bad traffic. Sometimes it blocks good requests by mistake. Look in your security plugin's logs or settings for a blocked request. If your server has a firewall rule, you cannot see it from WordPress.

Step 6: Ask support

Open a ticket at https://secure.hostvento.com/submitticket.php. Include the page address, what you clicked and the time of the error, so the team can check the server logs.

Quick recap

  • A 405 means the server refuses the request method.
  • Check the site address settings.
  • Test plugins and the theme.
  • Rebuild the .htaccess file.
  • Ask support to check the firewall and logs.
