Drupal 7.x

how to troubleshoot this?

Has anyone made a browser extension to log into your Drupal homepage with a simple click of a button?

I have a custom content type with aprox 400 fields. When trying to add a new field the page refreshes and the new field is not created.

I have a module on my Drupal 7 site which displays data returned from an API call within a page template.

I recently updated the text on the template - this change has displayed on the development copy of the site, but the test copy of the site is still showing the old text. The two copies of the site are on separate servers with separate databases. Both copies pull in from the same Git repository, run 7.59, have the same dependencies, and get deployed using the same deployment procedure.

There is no "Add a new file" button!

How can I add  table of contents on the left side bar (www.hemelix.com). I want to put a content navigation page there.

I am using Drupal 7.59 and Garland theme.
