I needed to install an SMTP extension on Magento 2.2.7, so I installed Pageplaza Core and SMTP extensions, but these extensions didn't work, so I uninstalled them.
Now, when I try to enter at home, at admin page or execute a command line, I only receive this ugly error message:
Fatal error: Interface 'Interop\Container\ContainerInterface' not found in /usr/aplic_ICM/prod/web/gap_venta/vendor/zendframework/zend-servicemanager/src/ServiceLocatorInterface.php on line 17
How can I repair this?
