CiviCRM Community Forums (archive)

Hi, I recently upgraded Drupal from 6.11 to 6.15, and also upgraded CiviCRM from 2.1 to 3.1.3.

For the most part everything seems to be working properly. However, since the upgrade, I'm experiencing the following errors whenever I make changes within CiviCRM:

warning: preg_replace() [function.preg-replace]: Compilation failed: support for \P, \p, and \X has not been compiled at offset 1 in /var/www/vhosts/justice4michigan.org/httpdocs/sites/all/modules/civicrm/packages/IDS/Monitor.php on line 445.

I've seen a couple of other older threads with similar error messages, but since those date back to 2008 and haven't had posts in quite some time, i thought it best to start a new thread.

Any suggestions?

most likely your pcre library is old and does not support unicode. You'll need to upgrade this library. search on the forums for PCRE

Thanks...I just checked, and it looks like my version is:

pcre-6.6-2.el5_1.7

Is that fairly new?

Also, assuming that I'm unable to update the version for whatever reason, is it critical to do so? That is, will CiviCRM not work properly without it, or will it just cause those warning messages?
