Errore dual login con Firefox e chrome

[emiliocb4]

ciao,
Dopo aver letto mille thread su come configurare jfusion e phpbb3 continuo ad avere problemi di dual login con Firefox e chrome , invece funziona bene con internet Explorer e safari

Configurazioni:
- joomla master nell'autenticazione
- phpbb slave
- utentii allineati
-  Authentication Mod (e jfusion nelle configurazioni di autenticazione in phpbb)  abilitato
-cookie configurati con . Prima del nome dominio e con / come path su entrambi i componenti



 , ma con i due browser scritti su
1) non mi effettua il login automatico nel forum dopo essermi loggato nel sito
2) se tento di loggarmi direttamente nel forum
Fatal error: Cannot redeclare utf8_strlen() (previously declared in /web/htdocs/www.motoclubcastelliromani.it/home/phpbb/includes/utf/utf_tools.php:233) in /web/htdocs/www.motoclubcastelliromani.it/home/joomla/libraries/phputf8/mbstring/core.php on line 27

Vi inserisco anche il login checker fatto con jfusion
