Important: #98122 - Fix felogin variable name in TypoScript setup 

See forge#98122

Description 

The showForgotPasswordLink setting was renamed to showForgotPassword during the refactoring to fluid templates. It is now also renamed in the TypoScript setup.

The TypoScript constant name is not changed to keep compatibility.

Migration 

Use plugin.tx_felogin_login.settings.showForgotPassword instead of plugin.tx_felogin_login.settings.showForgotPasswordLink in TypoScript setup. And styles.content.loginform.showForgotPassword instead of styles.content.loginform.showForgotPasswordLink in TypoScript constants.
