Hi
I've just started with my very first site build in concrete5.

I've started with a standard layout, and things are working fine, until I try to add a page, then I get the following error:

Notice: Sorry, your PCRE extension does not support UTF8 which is needed for the I18N core in /usr/local/pem/vhosts/112563/webspace/httpdocs/nrt247.dk/concrete/libraries/3rdparty/Zend/Locale/Format.php on line 794 Warning: Cannot modify header information - headers already sent by (output started at /usr/local/pem/vhosts/112563/webspace/httpdocs/nrt247.dk/concrete/libraries/3rdparty/Zend/Locale/Format.php:794) in /usr/local/pem/vhosts/112563/webspace/httpdocs/nrt247.dk/concrete/startup/process.php on line 1219

Any ideas of what I'm doing wrong? I'm a complete newbie in this (also in php)
