mbstring is a  non-default  extension  that is not enabled by default   see this page of the manual        Installation      mbstring is a non-default extension    This means it is not enabled by   default  You must explicitly enable   the module with the configure option    See the Install section for details   So  you might have to enable that extension  modifying the php ini file  and restarting Apache  so your modification is taken into account    I don t use CentOS  but you may have to install the extension first  using something like this  see this page  for instance  which seems to give a solution     yum install php-mbstring    The package name might be a bit different   so  use yum search to get it  -
