Modules not updating with composer

This is not a bug but rather usually something on your end. I have seen:

• Opcache bugs and misconfigurations. Restarting the web server will reveal this one in some cases.
• Site owners not allowing Composer plug-ins to run, sometimes resulting in two instances of a module.
• Other…

You have to check the module’s info.yml file in its expected location in the first place in a situation like this.

Thanks for your quick answer...
I restarted the web server, then just in case, the whole server... and nothing...
In the point "not allowing the Composer plug-ins to run": how, if I recently upgraded from 9 to 10 with composer and all went well?
And about the module's info.yum in expected location... well, all modules I've got are in "/drupalroot/modules/"

Sorry for my ignorance, could you please clarify a little more so I am able to follow you...
thanks again!

What is the version of the module in its info.yml file? What is the precise version of PHP?

I should have first asked to see the composer.json file before offering help. Let’s see that please.

Ok, thanks again...
PHP Version 8.2.8
I composer.json I've got, I think this is what you're requiring:

require": {
        "composer/installers": "^2.0",
        "drupal/aggregator": "^2.0",
        "drupal/captcha": "2.0.4",
        "drupal/clipboardjs": "^2.0",
        "drupal/composer_deploy": "^1.7",
        "drupal/core-composer-scaffold": "^10.1.1",
        "drupal/core-project-message": "^10.1.1",
        "drupal/core-recommended": "^10.1.1",
        "drupal/core-vendor-hardening": "^10.1.1",
        "drupal/csv_serialization": "^3.0",
        "drupal/protected_forms": "2.0.3",
        "drupal/visitors": "^2.16",
        "drupal/w3css_paragraphs": "^1.0"
},

and info.yml files of the affected modules says:
core_version_requirement: ">=8"
version: '2.0.2'
project: 'protected_forms'

core_version_requirement: ^8 || ^9 || ^10
version: '8.x-2.15'
project: 'visitors'

I had to update two other modules: captcha and taxonomy_manager...
All went well updating captcha with composer while with taxonomy_manager persists the problem I have reported.

Hi there, I just have discovered why, at least in my case, modules don't update with composer...

My Drupal installation is a manual one where modules are located directly inside modules/ directory, on composer updating, files of updating modules go to /modules/contrib/ directory.

Instead of uninstalling and reinstalling modules which would take me a while, I have created hard links instead. That solves my problem...
I hope this helps
