Public bug reported: 1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu Ubuntu 16.04 LTS
2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center zabbix-frontend-php: Installed: 1:2.4.7+dfsg-2ubuntu2 Candidate: 1:2.4.7+dfsg-2ubuntu2 3) What you expected to happen Zabbix-server-mysql and zabbix-frontend-php were installed on Ubuntu 16.04 server from standard repositories. The server already had a working Apache2, MySQL and PHP7 installation. After installing, steps explained in here https://thedutchlab.com/blog /installing-zabbix-on-ubuntu-1404 were done in order to configure Zabbix databases and to enable php front-end. Note, as Ubuntu 16.04 comes with PHP7, I skipped the "php5-mysql" part from these installation instructions. Earlier, I have installed Zabbix servers from Ubuntu standard repos on top of 14.04 using the same instructions. The only difference was that those servers used PHP5. Apache modules were enabled and Apache was restarted. Zabbix server was started. I navigated to Zabbix PHP front-end page and it was expected to work normally. 4) What happened instead After I navigated to Zabbix PHP front-end page, an empty page was displayed and following was printed to Apache2 error.log: ---8<---8<--- [Sun May 15 11:44:20.935486 2016] [:error] [pid 27479] [client xx.xx.xx.xx:50298] PHP Fatal error: Uncaught Error: Call to undefined function mb_strlen() in /usr/share/zabbix/include/classes/user/CProfile.php:330\nStack trace:\n#0 /usr/share/zabbix/include/classes/user/CProfile.php(214): CProfile::checkValueType('index.php', 3)\n#1 /usr/share/zabbix/include/menu.inc.php(351): CProfile::update('web.menu.login....', 'index.php', 3)\n#2 /usr/share/zabbix/include/page_header.php(123): zbx_construct_menu(Array, Array, Array)\n#3 /usr/share/zabbix/include/views/general.login.php(30): require_once('/usr/share/zabb...')\n#4 /usr/share/zabbix/include/classes/core/CView.php(111): include('/usr/share/zabb...')\n#5 /usr/share/zabbix/index.php(117): CView->render()\n#6 {main}\n thrown in /usr/share/zabbix/include/classes/user/CProfile.php on line 330 ---8<---8<--- According to Zabbix server's logs, the server itself seemed to work normally.
