application/config/doctrine/proxies\__CG__ConcreteCoreEntitySiteType.php): failed to open stream: No such file or directory, concrete5

Question

When installing concrete5-8.3.1 locally, after installation it shows like this error message:

require(C:/xampp/htdocs/testconcrete5-8.3/application/config/doctrine/proxies__CG__ConcreteCoreEntitySiteType.php): failed to open stream: No such file or directory

How to solve this one?

Answer 1

Go to /dashboard/system/environment/entities and click on the red "refresh entities" button. That should solve your problem

Answer 2

I am not familiar with Concrete but if you have a Symfony Console or something where you can execute commands I would try the following:

doctrine:cache:clear-metadata                               
doctrine:cache:clear-query                                  
doctrine:cache:clear-result                                 

Note: I don't know if the commands above are available as part of Concrete I am talking from the Symfony side where when I have such issues that is how I fixed

Last but not least I would try to dump the classes using composer:

composer dump-autoload --optimize
