Drupal 7.x

I have created a virtual appliance that runs Drupal.  I cannot provide access to the appliance console but I would like to be able to update the Drupal site with new features and fix patches. 

Hosting software upgrades and patches is not a problem.  Creating them and applying them is where I need a better understanding please. 

Thanks for your time and thoughts.

After updating a site running 7.92 fro PHP 7.4 to PHP 8.1, the site crashes with 'Unexpected error'.

The log show the following

mod_fcgid: stderr: PHP Deprecated:  Optional parameter $feed_nid declared before required parameter $context is implicitly treated as a required parameter in /home/domains/vol3/162/1262162/user/htdocs/sites/all/modules/feeds/feeds.module on line 272,

Could someone please explain this?

I have an old Drupal site - running 7.43.  I cannot, at this time, upgrade Drupal. 

Drupal is configured to use a Solr 5.5.0 cluster.  Solr 5.5.0 is, as far as I know, the most current compatible version for Drupal 7.43.

Hypothetical view with name, date of birth and city.  I can sort using the header for any of those fields.  But what if I want to sort by city and then have it sort by name where the city is the same?  There doesn't seem to be any way to specify levels of sorting.  Intuitively, my users expect to be able to sort by name, then sort by city and have the secondary sort remain whatever the last sort was.  But it seems to go by some arbitrary value (perhaps nid or submission date) after the first sort value.

In Drupal 7, we must use many-to-many references. There are 2 of these entities:

sport events fitness facilities (physical places)
Following are some guidelines for the entity relation:

I have a D7 site in which my images (for years) have been installed in a separate directory ('filestore') at the base for the drupal installation. The group for that directory is http, and the configuration of the file system points to that location. The site renders properly (theme, images) except for the images under posts. For some reason, the image html is rendering as <img src="/filestore/<user>/filename", but while the file is under the filestore directory (under a user there) and permissions are all as required, the image does not render.
