To solve the issue for the Front End User Registration (sr_feuser_register): Frontend login security level must be set to “normal” or to “rsa”.
You have to put this line to your localconf.php file: ROOT Directory/typoconf/localconf.php“
Please put the comment at: $TYPO3_CONF_VARS[‘FE’][‘loginSecurityLevel’] = ‘rsa’;
and add new line $TYPO3_CONF_VARS[‘FE’][‘loginSecurityLevel’] = ‘normal’;
Thanks,
