Update to 2.1.0 broke site, had to disable/remove plugin

[bossanova808]

The move from besteadfast to jalendport is not going so well for me...Things appeared ok when I updated, and the migration ran successfully.

However, subsequently, am seeing errors loading all site pages.

Even a manual composer remove of the old, and require of the new, does not fix it, nor the more thorough:
rm -rf vendor/ && rm composer.lock && composer clear-cache && composer update

If the plugin is installed and enabled, the entire site fails to load with this:

I was overhasty in removing what I thought was some obsolete code as I was going through and renaming things; added the (evidently) necessary code back in v2.1.1. Sorry for the inconvenience! 😬
