Drupal 8.x

Hello, I am Jlopezg88 and I will tell you what my first contact with Drupal and git was. We will start with Drupal which seems more interesting and we will end up with git.
Firstly I want to tell you that a week ago I did not know that Drupal was accurate, I knew it was a CMS such as Wordpress or Joomla but with the peculiarity that it has a reputation for being very difficult to learn having a very high learning curve.

Hello,

I'm getting a blank page saying "The website encountered an unexpected error. Please try again later." when I try to import a currency (Currency module).
In the error log I see the following:

"Error: Call to undefined function Commercie\Currency\bcdiv() in Commercie\Currency\Currency->getRoundingStep() (line 187 of /home/deb71460n10/domains/.../public_html/vendor/commercie/currency/src/Currency.php) #0 /home/deb71460n10/domains/.../public_html/modules/currency/src/ConfigImporter.php(197) ........."

Hi,

I'm trying to configure the Trusted Host Patterns for a domain that is similar to below:

www.testsite.co.uk/v8

the v8 is the subfolder that the URL re-directs to under the public_html directory.

I have tried all sorts of combinations but I just can't get it to work. Any suggestions would be most helpful.

Many thanks in advance.

Drupal8 maintenance/updating is a nightmare.

1. It is readily apparent that Drupal 8 cannot be upgraded by hand because of the giant black hole known as the /vendor directory where core keeps 3rd party libraries/components, and where contrib modules also install yet more libraries/components, all of which must be tracked by various .json files in order to fully recognized by the system.

I have a Drupal installation in one website and hoping to install a Mediawiki on another website or location. How can I achieve Single SIgn on between these two websites? My Drupal installation is Drupal 8 . Are there any modules currently available ? If not what steps need to be considered in developing a single sign on between Drupal 8 & Mediawiki?

I have installed Drupal 8 on my example.com website. I want to install mediawiki on a subfolder called example.com/mediawiki. When I try to access example.com/mediawiki it is giving 403 forbidden error. I guess it is because of the rules in .htaccess . How can I fix it so that only example.com/mediawiki is accessible an Mediawiki can be safely installed there? Someone suggested me deleting .htaccess file. But that exposed whole Drupal files to external threats.
