Root composer.json requires classiebit/eventmie-pro ^1.8

The error message indicates that the root composer.json file requires version ^1.8 of the classiebit/eventmie-pro package, but the latest available version is 1.7.1.

One solution is to update the root composer.json file to require version 1.7.1 instead of ^1.8. To do this, open the composer.json file and change the line "classiebit/eventmie-pro": "^1.8" to "classiebit/eventmie-pro": "1.7.1".

Then, run composer update to update the dependencies.
