Troubleshooting: Colibri Plug-in Not Appearing

Setting up the Colibri plug-in for Website 1 and upgrading to the PRO version that came with coverage for five websites was a smooth process without any issues. However, when I installed and activated the Colibri plug-in for Website 2, nothing happened. Although it shows that the plug-in is active, it doesn’t appear on the WordPress dashboard or the header. I tried deactivating all other plug-in in the hopes of getting the Colibri plug-in to work, but unfortunately, it didn’t solve the problem. Additionally, I’m unable to access the plug-in for Website 2 and add the license key to get the PRO version installed. I would greatly appreciate your assistance in resolving this matter.
