I get an error like the title. The whole mistake is as follows. :
PHP Fatal error: Uncaught Error: Class 'Phalcon\\Di\\FactoryDefault' not found in /home/admin/web/example.com/public_html/public/index.php:15\nStack trace:\n#0 {main}\n thrown in /home/admin/web/example.com/public_html/public/index.php on line 15
I see that phalcon and other requirements work in PHP info. What could be the problem?
