Do you have the php curl extension installed?

If you were on linux, this would show if it were: php -m |grep curl

Also, https downloads at Moodle would prefer to talk to an https moodle server requesting to download a plugin.   If your server isn't running https there is a work-around provided.

See:

https://docs.moodle.org/24/en/SSL_certificate_for_moodle.org#Provide_the_CA_certificate_manually

While that URL says version 2.4 of Moodle same applies for all Moodles I've ever run ... 1.x through 3.2

Well, according to debug, it's a session key thang.   Sessions, by default, are stored in moodledata/sessions/ .. they can and do change for admin level users ... have actually watched session files grow for admin users during that admin users session.

So ... this is a guess ... manually remove all files found in moodledata/sessions/  Do that in non-prime time cause as soon as you remove the files, all users will have to re-acquire/re-establish a session.

Am assuming the session key is related to the session files.   Think those session keys are cached/stored and are generated/re-generated  from time to time.

Depreciated doesn't mean error ... but it does mean you might have reached a stage where your PHP might need upgrading.

Moodle version?  PHP version?

Check out:

https://docs.moodle.org/dev/Releases

for your moodle version and the release notes paying attention to any changes in requirements for minimal PHP compt.

Not a Windows person myself, but also see XAMPP ... that the packaged thang where one gets PHP, MySQL, Apache in one 'easy' installer?   Those things are usually not the flexible when it comes to needing an upgrade to one of the AMP stack.

Interesting to note, that in recent upgrades to sites and in checking the environment after those upgrades, see a notice, for the first time, that is making a recommendation the site run https.  And an issue with command line moosh in talking to Moodle for plugins ...

Maybe a Windows person would hop in here and assist ... I've taken this about as far as I can, being non-Windows person.

2.8 Moodle
Bug fixes for general core bugs in 2.8.x ended 9 November 2015 (12 months).
Bug fixes for security issues in 2.8.x ended 9 May 2016 (18 months)

https://download.moodle.org/releases/legacy/ where 2.8 files can be downloaded, say
PHP 5.4.4 is minimum but it is a known fact that higher versions of PHP could create issues with older Moodle software.

Your PHP 5.6 is higher than what is required for 2.8.
Don't think the XAMP packages for Moodle has ever packaged a higher than needed version of PHP.   (could be wrong, don't use Windows)

But, that's the reason for those Depreciated warnings.

https://docs.moodle.org/28/en/Complete_install_packages_for_Windows

I can't think of a good reason that anyone would want to install a 2.8 ... cept to tinker with it.

Again ... I've taken this as far as I care to take it.  You'll have to wait for someone who uses Windows.
