I'm trying to install Phalcon 3.0 on a server running CentOS 7, Apache 2.4 and PHP 7 (FastCGI).
I followed up the instructions provided by the official documentation, Phalcon is installed on my server successfully, the extension is enabled on php.ini configuration but when I run phpinfo() it doesn't show phalcon as an active extension.
I found following error message in php-fpm error logs:
PHP message: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/phalcon.so' - /usr/lib64/php/modules/phalcon.so: undefined symbol: php_json_decode_ex in Unknown on line 0
This message appears everytime I restart php-fpm service.
Could you please help to fix this issue?
