Hey Mario,

It seems like your server disable this few php function e.g. phpinfo and phpinfo , you can refer on my attached screenshot below.

Then I unable to check your site hitting what error message is because your server disabled show error function from your site php server.

I debugging until this part of code -> JoomlaFolder\administrator\components\com_easysocial\includes\crawler\helpers\simplehtml.php

Then I noticed the system can't pass this code ->

// LINE 2503 (count from your file)

			$charset = mb_detect_encoding($this->root->plaintext . "ascii", $encoding_list = array( "UTF-8", "CP1252" ) );

I believe your server already disable or never install this mbstring (mb_detect_encoding) in your php server.

Can you also consult with your webhosting provider to enable this mbstring in your server? (you also can refer on my attached screenshot below)

Keep us updated then.
