Unable to create/import trigger after upgrade to zabbix 1.8.3

[meng-kong]

I have upgraded from zabbix 1.6.5 to 1.8.3, subsequently unable to create trigger or import trigger to newly created host.

... and ?
any error message, does this happen with all triggers, what's the exact trigger expression that causes the problem ?

I'm creating simple trigger for unavailability via icmpping item. Following are the extract from httpd's error log:

1. "genereal" looks suspicious. did you modify the frontend ?
2. looks like php mbstring support is missing. see reports -> status of zabbix.

of course, make sure to use 1.8.3

Love how a post from 5 years ago saves my bacon tonight.

After OS Security patching changed my PHP version, I found the answer in #2 above.
