Mail Sending Problem.-roundcube error log attached.

[nishith]

Using Sendmail as an MTA & Roundcube as a webmail service,version 0.2 beta.

Right Now,I am having a very strange problem.Roundcube webmail is working fine but sometime,sending of some mails are not going out. Even I can not save that mail.

While checking roundcube mail logs, I found below error. The command to execute roundcube error is :-

tail -f /var/www/html/webmail/logs/errors

The Error is :-
PHP Warning:  htmlspecialchars() expects at most 3 parameters, 4 given in /var/www/html/webmail/program/steps/mail/compose.inc on line 529

Normal mails are going quickly & I don't have other issues in roundcube. But, this error is very strange for me. I am not a PHP programmer Guy,So it won't possible to find out perfect solution by reading PHP.INI file.

please help.
