"PHP Fatal error: Uncaught Error: Call to undefined function mb_strtolower()"

Make sure your PHP install has the required modules, probably "php-7.3-mbstring" in this case.

Are you using PHP8?

I've never seen this particular error before, but I don't use phpfastcache at all, it's only vaguely (questionably) useful on very very large deployments.

It seems you're missing the mbstring functions in your PHP install, did you do something to PHP at the same time?

Check that this module is installed, on Debian it'll be php-x.x-mbstring, where x.x is the php version. This is what I get on my ubuntu install :

root@dev:/opt/observium# dpkg -l | grep mbstring ii php-mbstring 2:7.4+75 all MBSTRING module for PHP [default] ii php7.4-mbstring 7.4.3-4ubuntu2.7 amd64 MBSTRING module for PHP root@dev:/opt/observium#

Adam.

Hi Adam,

I ran this

sudo svn --config-dir /home/jstanford/.subversion update /opt/observium && /opt/observium/discovery.php -u

and it took me to the latest release. discovery and poller are both erroring out with the same error. I haven’t rolled back the code yet in case you needed me to test something.

php-mbstring module is recommended for install by default.

Anyway after NY I will check this library (phpfastcahe) for use without this module.

I think I fixed it. As usual, I went back and looked at the install docs. It seems they have changed since I had installed on Deb 10. When I checked the packages, php7.3-bcmath php7.3-curl php7.3-mbstring were missing. I installed them and it’s working now. (mbstring probably being the fix).
