Support Start > Outdated Browser Blocking

If you were given a link to this page as part of an error message, you’re probably using an outdated web browser. We block access to certain pages from these browsers because they’re usually “bots”.

You can probably work around this by updating your web browser, or using a different modern web browser like Firefox.

Is this your site?

If this is your website, and you want to completely and permanently disable this type of blocking for it, you can do so by adding this line to your site’s .htaccess file:

SetEnv tigertech-outdated-useragent-blocking disable

If you do this, keep in mind that it removes some (not all) of the protection we offer against “botnets” that impersonate old web browsers.

All modern consumer browsers automatically update themselves to the latest version. We list exceptions for certain version combinations that can’t be updated to make sure they aren’t blocked (for example, we wouldn’t block Chrome “long term support” version 109 on Windows 7 or Windows 8, because that’s the latest version that supports those platforms), but we can generally detect which browsers could be updated to a newer version.

If a browser could be updated to a new version, but hasn’t been updated, it’s almost always a bot. Preventing them from accessing certain security sensitive pages (as part of a multi-layered defense) improves security by blocking many attacks even before other rules are considered.

Can I allow just a single outdated user agent?

If this is your site and you want to allow just one single outdated user agent, you can modify the line with an <If> statement, like this:

<If "%{HTTP_USER_AGENT} =~ m'Chrome/116.0.0.0'">
  SetEnv tigertech-outdated-useragent-blocking disable
</If>
