This usually means that the server doesn’t have the php-mbsting enabled.
When rebuilding Apache with Easy Apache, on step 6 (exhaustive options), scroll down and check php-mbstring.
Then let it compile as usual.
Mine had an alert near the end of the make process “No package php-mbstring available.
Error: Nothing to do”
However it fixed the problem!
Another way to enable php-mbsting is manually run in SSH shell as root:
“yum -y install php-mbstring”, then “service httpd restart”
Mine couldn’t find php-mbstring, but that’s probably just a matter of adding the right repository to yum.

In my phpinfo screen, my server now says this:
mbstring
| Multibyte Support | enabled |
| Multibyte string engine | libmbfl |
| HTTP input encoding translation | disabled |
mbstring extension makes use of “streamable kanji code filter and converter”, which is distributed under the GNU Lesser General Public License version 2.1.
