Drupal 7.x

I'm a beginner in Drupal and I'm helping to administer a site djanemag.com, but the problem is the look of the main page that is without the graphics and all messed up according to the print. However, the other pages are working perfectly. 

I get an error while editing fields of views in Drupal site. It says:

"

An AJAX HTTP error occured

HTTP Result Code: 500

Debugging information follows

Path: system/ajax

Status Text: Service Unavailable (With Message)

Response Text:

"

I have tried increasing max_execution_time to unlimited (0) and memory_limit to up to 1024M in drupal settings.php as I do not have permission to edit default php.ini in the system. However, the Error persists. Can anyone help me with it?

Thank you

Hello,

I have an issue when someone or when I publish something on drupal website, for some reason when i create a new draft and press save, this is not shown on the website and does not appear anywhere on moderate,but, if i create a new draft again with different content and publish it, the website shows the first draft I created before, it's like I'm 1 draft behind.

Do anyone know why this can be happening?

Thank you

I'm looking for a solution to this problem I've encountered.

What I am looking to do is have the webform auto populate one of the fields (lets call it "Job Number" with the information that is entered when creating the original Content.

For example, we have setup a job board with Views and Content Type:

I have used Dev Desktop for many years but now it is not working. 

I want to do all updating and developing on my own computer and then send it to my Hosting company. 

I have done it for years for two websites but now Dev Desktop is not working any more. 

I have used Drupal7 and now it is time to go over to Drupal9.  

What are my alternatives? 

I'm looking for a reference document of some sort that is geared toward experienced Drupal 7 developers who want to have an easy reference for the "new way" of doing various things.  Ideally, I'd love to find something that has a before and after reference for all the hooks, functions, and techniques that were standard in 7 that are no longer functional in 9.  Something I can refer to when I want to do the things I've done a thousand times before but now its all different.
