Error on WordPress after activating plugin

I added the plugin “clickfunnels” and at the moment I activate the plugin wordpress gives a critical error in all areas.

Access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), navigate to /wp-content/plugins/ and rename or delete the directory of clickfunnels plugin.

Next, report the issue at that plugin’s support forum at https://www.ads-software.com/support/plugin/fast-clickfunnels/

Hi @khalavos,the critical error can be due to –
1.`ERR_CONNECTION_TIMED_OUT
2.ERR_CACHE_MISS
3.500 Internal Server Error
4.Error Establishing a Database Connection
5.HTTP 503 Service Unavailable
6.HTTP 502 Bad Gateway`
