Errors related to missing MetatagServiceProvider.php after upgrading to 2.0

Please rebuild your caches, that should make the problem go away, please let me know if it doesn't.

I've tried that a few times (also tried using drush cr). The action of clearing the caches is actually what triggers this in the logs.

If I don't clear the caches there are no new errors like this in the logs.

Can you please check your site's codebase to see if anything else might reference MetatagServiceProvider? Thank you.

I've done a search and haven't found anything. Also searched the database, and no luck there either (except for references in Watchdog).

The only other related plugin installed on this site is schema_metatag 3.0.1. I'm not aware of anything else that would be calling MetatagServiceProvider.php

These are the full error messages I'm seeing.

Warning: include(): Failed opening '/home/XXX/d10/web/modules/contrib/metatag/src/MetatagServiceProvider.php' for inclusion (include_path='/home/XXX/d10/vendor/pear/archive_tar:/home/XXX/d10/vendor/pear/console_getopt:/home/XXX/d10/vendor/pear/pear-core-minimal/src:/home/XXX/d10/vendor/pear/pear_exception:.:/opt/cpanel/ea-php81/root/usr/share/pear') in include() (line 571 of /home/XXX/d10/vendor/composer/ClassLoader.php)

Was installing 2.0 (via composer) directly on top of 8.x-1.26 the proper way to update, or should have I followed a special process?

Thanks for the help!

Ok, as a last resort I did a quick restart of the server and can no longer reproduce these errors.

Strange, but fixed I guess.

Thanks for letting me know. I suspect something was stuck in the opcache and it wasn't reloading the class list. I've updated the 2.0.0 release notes to mention this.

Automatically closed - issue fixed for 2 weeks with no activity.
