Drupal 7.x

I load up Google Chrome and hit the F12 key to load up Developer Tools. After I clear my cache, I go to the Network tab and record a page load. I load up my homepage to my website and Google Chrome says it's taking 35.58 seconds to fully load. How do I isolate where the problem is? Chrome gives me these figures:

Status: 200

Type: document

Initiator: Other

Size: 43.1 kB

Time: 35.58 s

I hover my mouse over the Waterfall bar graph and it indicates that most of the time is spent on "Content Download".

I have installed Drupal 7.72 on php 7.4, I am getting following error message :

Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in include_once() (line 1387 of /home/public_html/includes/bootstrap.inc).

Line no. 1387 of bootstrap.inc is as below

  if ($filename) {
    include_once DRUPAL_ROOT . '/' . $filename;
    $files[$type][$name] = TRUE;

    return TRUE;
  }

Has anyone come across a module that has a field to upload a document and save it to Google Drive?

This is the error message: Notice: Trying to access array offset on value of type null in include() (regel 33 van /customers/6/2/d/seniorama.be/httpd.www/sites/all/themes/Thema1N/node.tpl.php).

This is the website: www.seniorama.be

For the site in question, some registered users don't display in “People,” but do display if a View is created to display all users. What could explain this? Is there a limit on the total number of users displayed under “People”?

(Clarifying: Despite the paging aspect; all pages there have been searched.)

Possibly relevant info: The Drupal version in question is 7.67. Users are added via User Import module.
