Upgrading Drupal

Do we need this file?

vendor/symfony/console/Resources/bin/hiddeninput.exe

Hi All,

I'm not all that technical these days having been taking a break over a few years so please excuse my ignorance.

I run a site for a club I'm a member of which is currently on Drupal 7.89 with the Garland theme. The site bofa76.org.uk isn't rendering correctly anymore and I'm not sure if thats due to a recent upgrade or if its to do with IE being depreciated and things being different via Edge. Chrome by the way gives the same behaviour.

I tried to update my drupal version from 9.3.9 to 9.3.11 with composer. Now composer info drupal/core-recommended shows version 9.3.11 but drupal still says I use 9.3.9. I also checked the date of files in drupal/core - it's from 14th of April, so I think it is 9.3.11. Any suggestions about this?

Attempting to upgrade from from D7 to D8 or D9.

I get an error when migrating comments module.  I have searched for a solution without success. 

The error in the migrate UI is:

Migration d7_comment did not meet the requirements. Missing migrations d7_node_complete:story. requirements: d7_node_complete:story

The site is hosted on Hostinger using PHP 7.4

I'm hoping this is something obvious that I am missing.

I'm trying to upgrade a site from D7 to D9 using the drush migrate-import command.  It is failing with this error.
