Drupal 8.x

Hello,

I have a content type consisting of a few fields (images and text of various lengths). When I have a piece of content created, I'm unable to edit the fields, however. Here's the edit process and the result:

If I want to create a new module to store the image on Third-party webserver(such as dropbox), what should I do? I don't understand the Drupal 8 file system, Can you give me some advice? Such as link or article. Thanks!

So what I want is this:

form page 1:
-- you pick and option

form page 2:
-- you fill out the rest of the information

form page 3: (or just payment)
-- Stripe payment screen pops up without you pressing the pay button.
Completed payment triggers formSubmit()

I have the form part but no idea on the Stripe payment. Ideally I am trying to only save and process the form is the payment is good.
Can you do a java something (I no no java) based on the form step?

How do I go about outputting the display of content type fields on a page or in a block for users to submit data to? (such as a Testimonials content type)

In D7, I was able to use some PHP to render the content type fields in a block but it doesn't seem like that's the case anymore in Drupal 8.

Hi,

I installed Drupal 8 with WAMP and everything has gone really well...until I have tried to link pages on my site to images and specifically a pdf. I checked forums here and internet, changed httpd.conf, but still getting that 403 Error that says "You don't have permission to access /drupal8/..sites/default/SiteFiles/(PDF) or (image, etc.) on this server.

Am I missing something really easy?

Thanks in advance,

Michael

I'm getting an exception that only happens when I view my development site as an anonymous user. I can't find any similar issues and am stuck. I guess it's linked to a module, but the exception mentions a core module that I can't uninstall. When something like this happens what should I be doing to fix the problem? I use a large number of modules so trial and error uninstallation of them would be difficult. Any help would be very much appreciated, thanks!
