Drupal 8.x

I have upgrade Simple Oauth module from 3.8 -> 4.3.

I already tried https://www.drupal.org/project/simple_oauth/issues/3056439 But I am still getting below errors

League\OAuth2\Server\Exception\OAuthServerException: The resource owner or authorization server denied the request. in League\OAuth2\Server\Exception\OAuthServerException::accessDenied() (line 223 of /vendor/league/oauth2-server/src/Exception/OAuthServerException.php).

In my Drupal 7.62 site, the Field List report shows these 2 fields, which can be configured, thru the File Entity module, at Configuration / Media / File Settings. The fields are used as part of certain tokens to set the default "alt" and "title" tags at that File Settings page.

Hello there! I upgraded my website to 8.8.1 - apparently successfully. Now the build-in function to check and upgrade modules does not work any longer. When I click "check for available updates" the batch?id=70&op=start seems not to be executed. Drupal tells me that the process is initialised - but nothing happens. The same situation occures when I click on updating certain modules such as "token". The update function worked before the core update.

Does anyone have a clue? Thanks in advance!

Language selection module 8.x.2.3. I have 2 languages enabled, each setup with it's own url /en & /fr. The detection and selection has the correct order

 URL > Cookie > Language Selection page > Selected Language

The standalone template has been set and the html--language-selection.html.twig page created from html.html.twig.

When I visit the site www.mysite.com/language-selection it immediately redirects to the front page mysite.com/en.

I am migrating a site from D7 to D8. I have several content types that allow for unlimited taxonomy terms. In D7 the terms are entered in one field separated by commas (ex: term1, term2, etc). 

In D8 it appears that one has to click "add another" each time an additional term is added. If I try adding multiple terms separated by commas they get entered as one terms. For example in D8 it appears that entering: term1, term2 becomes one term "term1, term2." 

I have set up a drupal site on an apache webserver on my localhost.

Navigating to any .module files, I am able to view them, e.g. localhost/core/modules/user/user.module

I am unable to view any .php files.

I can see in the .htaccess file there seems to be code to prevent .php files being viewable. Should there be something similar for .module files?
