"phpmyadmin Error - mbstring The mbstring extension is missing. Please check your PHP configuration." After the installation of additional php5.6, the phpmyadmin show this error. Before it was working. The system run the same php 7.0 than before. I have read many threads on this error but I cannot find a solution. I suppose I shouldn't recompile because before it was working. I have enabled the extension inside /etc/php/7.0/cli/php.ini and rebooted the machine, and the error persist Code: # php -v PHP 7.0.33-0+deb9u1 (cli) (built: Dec 7 2018 11:36:49) ( NTS ) Copyright (c) 1997-2017 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies with Zend OPcache v7.0.33-0+deb9u1, Copyright (c) 1999-2017, by Zend Technologies Code: # php -a Interactive mode enabled php > echo extension_loaded('mbstring'); 1 Code: # php -i | grep php.ini Configuration File (php.ini) Path => /etc/php/7.0/cli Loaded Configuration File => /etc/php/7.0/cli/php.ini Code: # php -i | grep mbstring /etc/php/7.0/cli/conf.d/20-mbstring.ini, Zend Multibyte Support => provided by mbstring mbstring mbstring extension makes use of "streamable kanji code filter and converter", which is distributed under the GNU Lesser General Public License version 2.1. mbstring.detect_order => UTF-8 => UTF-8 mbstring.encoding_translation => On => On mbstring.func_overload => 0 => 0 mbstring.http_input => auto => auto mbstring.http_output => UTF-8 => UTF-8 mbstring.http_output_conv_mimetypes => ^(text/|application/xhtml\+xml) => ^(text/|application/xhtml\+xml) mbstring.internal_encoding => UTF-8 => UTF-8 mbstring.language => neutral => neutral mbstring.strict_detection => Off => Off mbstring.substitute_character => no value => no value Code: # cat /etc/php/7.0/cli/conf.d/20-mbstring.ini ; configuration for php mbstring module ; priority=20 extension=mbstring.so Code: # locate mbstring.so /usr/lib/php/20151012/mbstring.so Code: # htop 682 root 20 0 470M 45280 36460 S 0.0 0.3 0:00.13 +- php-fpm: master process (/etc/php/7.0/fpm/php-fpm.conf) 917 www-data 20 0 469M 10880 2060 S 0.0 0.1 0:00.00 ¦ +- php-fpm: pool www 916 www-data 20 0 469M 10880 2060 S 0.0 0.1 0:00.00 ¦ +- php-fpm: pool www 915 web9 20 0 469M 11072 2252 S 0.0 0.1 0:00.00 ¦ +- php-fpm: pool web9 some idea?
