Drupal 7.x

Hello all,

One of our Drupal 7 website has been hacked after critical vulnerabilities :

   https://www.drupal.org/sa-core-2018-003
   https://www.drupal.org/sa-core-2018-004

I disconnected the server and I am currently reinstalling the website is reinstalled on a freshly installed server.

My questions are :

Hello,

I want to sell my digital products (PDFs, PPSX files or zip files) on drupal 7. I want to learn a good, trustworthy payment method which can be used in drupal commerce to sell digital products. I've already downloaded commerce file to sell my items. I'm not sure how to control the gateway to the paid file. When the user buys the digtal product, then he should be allowed to access to the file. What's the suitable payment way for this task?

Using latest Drupal 7.

I cannot figure out WHy CK editor is not showing in a text are, module neabled, permissions granted.

I cannot configure it, links don't work.

What am I missing/

Very strange problem.  On one of my websites I am not able to add or modify fields to any content types (I am simply wanting to add an Image field, which I have done very easily on many other Drupal sites).  I verified that permissions "Administer Fields" and "Administer Content Types" are granted to Administrator.  However, when I go to Structure -> Content Types, there is no links to "manage fields" or "manage display".  What am I missing?  I didn't think it required any special module, right?  All of my sites are currently Drupal 7.59.  Please help?!?

I've created a custom module with the following code:

Hi,

Going to a View, after choosing some Fields like "Title", "Teaser", "Link" etc. I choose to Rewrite results for the Link and "output this field as a link". I then enter "button" under the Link Class so that to show links as buttons.

As per my expectations, the preview generates buttons instead of links.
However, on the actual page, links don't show as per the preview and continue to show as links.

Any thoughts would be highly appreciated

Cheers
