I’m running an woocommerce setup and was trying to get a product input field for custom text from customer, after trying out Booster (https://booster.io/) it seemed a bit much for what I needed with all the extras, so I uninstalled it.

Since removing Booster, areas of my “Add Plugins” section won’t load with message:
“An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums” via the ajax response.

Featured loads fine, however Popular|Recommended|Favorites, and searched all return the message above.

The rest of my site works, I can navigate, submit orders, log in/out of admin dash, add products, etc. The only thing that doesn’t seem to work is the ability to add a plugin since removing Booster.

I’ve enabled the WP_DEBUG_LOG, which has given me an indication that is_page() and is_singular() were called incorrectly, however it references wp-includes/function.php:5663 which seems to just be where the error was caught and reported..

At a standstill as I can’t seem to figure out how to fix this error. Any assistance would be appreciated.
