Topic: "String functions are overloaded by mbstring"

Hi.I am unable to install PunBB on a CentOS linux server with PHP 5.2.5.

I am seeing this when I execute the "install.php" in the admin. 

Fatal error: String functions are overloaded by mbstring in /home/MYDOMAIN/public_html/forum/include/utf8/utf8.php on line 42

I did some googling and found that this error is related to the "mbstring.func_overload = 7" setting in PHP.INI. We are running a multilingual website and wish to support utf8 completely, so that setting cannot be changed.

Does this mean we cannot install PunBB?

Re: "String functions are overloaded by mbstring"

You have two options, change it for just this 1 site, or change it for eveysite. Option 2 will change it for just this site.

Option 1: In your php.ini you will have

mbstring.func_overload = 7

But it should be:

mbstring.func_overload = 0

Option 2: adding this line to .htaccess


php_value mbstring.func_overload 0
