PHP option "mbstring.func_overload"

[WSP-Computer]

Hi All,

just installed zabbix 3.4 configured in best matter.... But I can't remove the Error: PHP option "mbstring.func_overload" must be disabled.

I have edited php.ini as described.

Restart Server with init 6

System: Ubuntu 16.04.2, installed with repo with actual get-update..

Maybe any help outside?

Thx,

Wolfgang

Hi Wolfgang!
Welcome to the Zabbix Community

Check please if you have a symlink in /etc/apache2/conf-enabled/ name zabbix.conf which is pointed to /etc/zabbix/apache.conf ?

It should override the default configuration of your php.ini file, otherwise it seems like in your php.ini file you have enabled ;mbstring.func_overload = function.

Hi Alex,

I have check it but it seems OK:

/etc/php/7.0/apache2/php.ini
; overload(replace) single byte functions by mbstring functions.
; mail(), ereg(), etc are overloaded by mb_send_mail(), mb_ereg(),
; etc. Possible values are 0,1,2,4 or combination of them.
; For example, 7 for overload everything.
; 0: No overload
; 1: Overload mail() function
; 2: Overload str*() functions
; 4: Overload ereg*() functions
; http://php.net/mbstring.func-overload
;mbstring.func_overload = 0

; enable strict encoding detection.
; Default: Off

zabbix.conf:

<Directory "/usr/share/zabbix">

can u help?

First thing in zabbix.conf - uncomment the php_value date.timezone Europe/Riga and second - check if you have the file zabbix.conf in /etc/apache2/conf-enabled/ , which is symlinked to /etc/zabbix/apache.conf. You can check it with readlink command:

readlink -f /etc/apache2/conf-enabled/zabbix.conf

.

One more thing, errors during the frontend installation wizard?

Hi,

I uncomment lines... But no change.

Symlink:

root@ubuntu-zabbix:/etc/apache2/conf-enabled# readlink -f /etc/apache2/conf-enabled/zabbix.conf
/etc/zabbix/apache.conf
root@ubuntu-zabbix:/etc/apache2/conf-enabled#

Seems ok....

There are no failures through Setup...

Did u have any other idea?

Thx,

Wolfgang

Hi,
So you are getting this error in Dashboard ? Could you please post a picture here?

I've jsut installed the fresh 3.4.1 with mysql and frontend on 16.04.3 - everything is just fine. You are installing it on fresh ubuntu or it was used by any other web-app before ?

Alex!
