Drupal 8.x

I'm trying to make a website for a non-profit where payed customers get a bit extra stuff when we meet offline. So I wanted users with a certain role to have "pain until" date field, and let users extend their subscription for however much they want using paypal, maybe have the site email them when the date of that field is approaching.

Drupal commerce seems big and heavy with a ton of dependencies that I've never used. My main job is a developer. I know php, though I've never developed a Drupal module.

I've been using Drupal and Wordpress side by side for freelancer projects. I've chosen a platform depending on the scale and client. Now, after I transitioned into using Drupal 8 I might have to move completely to Wordpress as I am experiencing massive performance issues running the platform on a local setup. Production runs better, but that might have to do with caching.

Help me please. When you install drupal-8.2.5 such a mistake at step 'Install site'

In order to run the following composer utility command to install Drupal 8, it is necessary to increase available PHP memory to nearly 1GB of memory!!!!!

composer create-project drupalcommerce/project-base mysitedir --stability dev

On a D8 site, when I run the composer outdated command to check for components that need updating, composer produces a list, as follows:

php composer.phar outdated

All of the sudden I lost functionality of several buttons on my Drupal 8 text editor.

I click the link button and nothing happens. A few other buttons don't work either such as Video embedded. The buttons don't work on both Full and Restricted text editor mode. Everything was working fine. Didn't make any changes or install any modules.

Please help as I have no idea what could be the problem or what to do next.
