Server configuration
Database: MySQL 5.5
PHP version: 5.6
ownCloud version (see ownCloud admin page): 9.1.4
Updated from an older ownCloud or fresh install: NEW

In error log serwer i have:
Got error 'Passing INI directive through FastCGI: unable to set 'mbstring.func_overload'\n'
every 30 sec when my pc app is online ;/
I can not turn on php 7 because I get rid of other pages
I suspect that sometimes it does not work OwnCloud then just plug it in for a while php7 and when it switches to 5.6 it works again. How to get rid of these errors?


if you're running FastCGI / fcgi and so on you're mostly on your own when having such issues. Its highly advised to use one of these combinations when running ownCloud:

Apache + mod_php (officially supported and the only platform ownCloud is tested with)
nginx + php-fpm (Community support, people are familiar with such a setup and can help with issues arise)
