Current Releases: Known Issues

All Techs

Applies to: .NET v4.3.2, Java v4.0.Beta3.4, and PHP v4.2.2

  • Captcha Audio fails to play in the UC Browser on Android.
    The issue does not affect the UC Browser on iOS.
    The issue does not affect the UC Browser on Windows.
    We are still investigating the root cause of it.
  • Captcha audio in Safari on iOS 12 is not supported yet.
    Some folks in Apple believe that not changing the User Agent string pattern in an unexpected way in the each new minor iOS release will bring Apple a year worth of bad luck -- yep, they did it again :(.
    This is already fixed and the fix will be included in the next minor release.

Issue Pipeline:

  • None.

.NET v4.3.2

  • If the culture of a thread in which BotDetect runs uses language not written in the Latin-1 script all requests to BotDetect.ashx Captcha handler will result with Internal Error 500 due to attempt to add invalid (non-ASCII) characters to response header.
    The issue affects .NET Core 1 and .NET Core 2 builds.
    The issue does not affect legacy .NET builds.
    This is already fixed and the fix will be included in the next minor release.

  • Captcha is not displayed in the IE11's Emulation of the IE9 and IE10 Document mode.
    The problem does not exist in the IE10's or Edge's Emulation.
    The problem does not exist in the real IE9 and IE10.
    This is already fixed; and the fix will be included in the next minor release.

Issue Pipeline:

  • None.

Java v4.0.Beta3.4

Simple API (Experimental):

  • The "java.sql.SQLSyntaxErrorException: object name already exists" log entries pile-up in the application error log if your app uses the org.hsqldb artifact version lower than v2.3.4.
    While being annoying, it does not affect neither Captcha nor your application functionality.
    The workaround is to upgrade the org.hsqldb artifact to the version v2.3.4 or higher.
    This is already fixed and the fix will be included in the next minor release.

  • Captcha is not displayed in the IE11's Emulation of the IE9 and IE10 Document mode.
    The problem does not exist in the IE10's or Edge's Emulation.
    The problem does not exist in the real IE9 and IE10.
    This is already fixed; and the fix will be included in the next minor release.

Traditional API & Simple API:

  • If there are multiple Captchas on a page, and each of them is in a different PrimeFaces tabView, and the tabView's toggle mode is set to true, only the Captcha in the first tab will load successfully.
    The workaround is to set the toggle mode to false: <p:tabView dynamic="false">.
    We are still investigating the root cause of it.
