Are you getting error below error in wordpress while installing plugin ?

“An unexpected error occurred. Something may be wrong with WordPress.org”  The solution for this issue is to check file wp-config.php

While troubleshooting issue I see the error was in wp-config.php

I commented out below settings to fix this issue

/** EXAMPLE – proxy settings */
#define(‘WP_PROXY_HOST’, ‘proxy.url.com’);
#define(‘WP_PROXY_PORT’, ‘1234’);
#define(‘WP_PROXY_USERNAME’, ”);
#define(‘WP_PROXY_PASSWORD’, ”);
#define(‘WP_PROXY_BYPASS_HOSTS’, ‘localhost’);

This issue got fixed once I commented the above settings.
