Invalid argument supplied for foreach () in [path] / includes / class_postbit.php (294)

[Valdo]

Since I have upgraded vbet, whenever I rename a discussion of this error:

Warning: Invalid argument supplied for foreach () in [path] / includes / class_postbit.php (294): eval () 'd code on line 27

Warning: Invalid argument supplied for foreach () in [path] / includes / class_postbit.php (294): eval () 'd code on line 27

How do I fix this?
Thanks

Da quando mi hai aggiornato il vbet, ogni volta che rinomino una discussione mi da questo errore:

Warning: Invalid argument supplied for foreach() in [path]/includes/class_postbit.php(294) : eval()'d code on line 27

Warning: Invalid argument supplied for foreach() in [path]/includes/class_postbit.php(294) : eval()'d code on line 27

Come lo risolvo?
Grazie
