Upgrading Ubuntu server to 22.02 and PHP version to 8.1 gives `spl_autoload_register()` error

[gobs]

I upgraded my Ubuntu server from 18.02 to 22.02 and my PHP version to 8.3 (from 7.4). This then gave me the following error:

Whoops \ Exception \ ErrorException (E_NOTICE)
spl_autoload_register(): Argument #2 ($do_throw) has been ignored, spl_autoload_register() will always throw

You can see the full error on my site and I’ve also attached a screenshot.

I thought that downgrading to PHP version 8.1 might help, as would removing the shortcode plugin, but no, same error Any ideas?

Additional context:

• System output log just gives me the same error: spl_autoload_register(): Argument #2 ($do_throw) has been ignored, spl_autoload_register() will always throw
• Grav admin panel works, my actual website does not
• I’m running Nginx
• Tools → Reports does not indicate any errors
• These two questions are the most relevant to my problem, but did not help:

Upgrading from php7.4 to php8.1

I am upgrading from a perfectly working (and current) grav installation of php7 to php8. The admin pages seem to work fine, but the main homepage seems to give me this rather evil error: Server Error Sorry, something went terribly wrong! E_NOTICE - spl_autoload_register(): Argument #2 ($do_throw) has been ignored, spl_autoload_register() will always throw For further details please review your logs/ folder, or enable displaying of errors in your system configuration. I have looked into things…

Server Error: E_NOTICE - spl_autoload_register()

Hello, I am having some issues that began after updating to v.1.7.5. First the site was blank (see my post here). I updated, again, to v1.7.7 and updated PHP to v8.0. Then I got an error with the MATOMO plugin. I uninstalled the MATOMO plugin and now I am having the following error: ### E_NOTICE - spl_autoload_register(): Argument #2 ($do_throw) has been ignored, spl_autoload_register() will always throw The last input at the log file can be see here: https://moleculardocking.net/grav.log…

Did you read the pinned topic about asking questions? Did you try to search the forum?

[gobs]

Hi @Karmalakas ! Yes I have (read the pinned topic and searched the forum). I will admit though that I am not keen on creating an MWE, since this would be quite some effort for me. I have updated the post to provide more context.

Are there plugins other than shortcode that could be throwing this error?

[gobs]

Yes there are - Media Embed, last updated from 2017. I disabled it and everything is fine now So I guess this is a general rule, some plugins may break Grav when updated PHP versions.

It makes ense, that old outdated plugins use PHP features, that are no longer supported on newer PHP versions. You could raise an issue on GitHub plugin repo. Might get updated if plugin author is up for it
