And that you’re trying to install Square from the repository directly from the plugin search in your WP Admin, correct? * Please share with us the necessary information below for us to investigate the issue further: - **System Status Report** which you can find via WooCommerce > Status > Get system report > Copy for support. - **Fatal error logs** (if any) under WooCommerce > Status > Logs. * You could copy and paste your reply here or paste it via [https://gist.github.com/](https://gist.github.com/) and send the link here. * Once we have more information, we’ll be able to assist you further.
