Drupal 8.x

I created a page in a custom module. I want only the current user to access this page on their behalf.

For example, I am using it with ID 51. If I go to :

/user/51/tasks

I can see this page.

If I go on :

/user/78/tasks

I must have an error 403 access denied.

How to do this ?

We have a typical 3-part environment for our website - Development / Staging / Production.

Is there an easy way, plugin or other tweak that can prevent modules from being updatable in the Production environment? Something that prevents a user from making unwanted code changes in the live site. When we copy down code to the Dev. environment, I would like that ability to update available though.

... or a server-side solution that I could propose to the server administrator?

I am trying to synchronize settings between a dev install and the production install.  At one time I enabled and disabled the Field Layout module and I am not sure if that has anything to do with this error.  I have searched all over google but nothing really makes sense or apply.  When I do the import or the Drush cim I get this error:

[error] Drupal\Core\Config\ConfigImporterException: There were errors validating the config synchronization.

Hi everybody,

Hi Everyone,

I am developing a web application with Drupal 9.

My local environment is Windows with Apache 2.4, PHP 7.3 and MySQL 5.7. I was in need of deploying it to UAT for testing purposes. The UAT environment is Ubuntu with Nginx, PHP 7.3 (FPM) and MySQL 5.7.
