install php mbstring extension debian jessie

So, the module is there and looks installed/available, but still, cacti keeps erroring as if it weren't there. Gargamel:/etc/cacti# php -m | grep mbstring With Zend OPcache v7.3.12-1, Copyright (c) 1999-2018, by Zend Technologies Zend Engine v3.3.12, Copyright (c) 1998-2018 Zend Technologies I spent hours trying to fix this and getting mbstring working (which clearly is not default in php for reasons I don't understand). PHP Fatal error: Uncaught Error: Call to undefined function mb_strlen() in /usr/share/cacti/site/lib/rrd.php:1639 Stack trace: #0 /usr/share/cacti/site/graph_json.php(158): rrdtool_function_graph(93, '0', Array) #1 thrown in /usr/share/cacti/site/lib/rrd.php on line 1639, referer. I still get this in my apache logs each time I open a cacti page: I did just upgrade it to 1.2.7+ds1-1 as packaged by debian.

I can't believe how terrible php has been handled this complete incompatible upgrade and forcing a flag day as opposed to supporting both versions side by side like perl or python.Īnyway, after this forced php7 upgrade (pulled by another package I had to upgrade), plenty of things broke, and I haven't been able to get cacti working since then. I've had cacti working for close to 10 years on linux/debian and upgraded it multiple times.Īnd then the php5 to php7 upgrade from hell happened (I'm not even going to go into php 7.0 vs 7.2 vs 7.3).
