Uncaught Error: Cannot instantiate interface

[kweste]

I've installed Magento using one-click install on my host. I tried to install a theme. I moved over all of the theme files and ran php magento/big setup:upgrade, but I get the following error:

Fatal error: Uncaught Error: Cannot instantiate interface Magento\Framework\Url\RouteParamsPreprocessorInterface in /home/customer/www/xxx/public_html/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php:73
Stack trace:

I've tried clearing my cache, but it doesn't make a difference.

Hi @kweste ,

can you check that in your custom theme all the required files are present. or once you can remove the theme and check in default it work fine or not if this work for you accept this as solution and give kudos.
