When I attempt to uninstall the extension, it crashes the website with the following error.  

Warning: require_once(/home/easttexasnews/public_html/j4dev/components/com_cjlib/framework.php): failed to open stream: No such file or directory in /home/easttexasnews/public_html/j4dev/plugins/content/cjforum/cjforum.php on line 19Fatal error: require_once(): Failed opening required '/home/easttexasnews/public_html/j4dev/components/com_cjlib/framework.php' (include_path='.:/opt/cpanel/ea-php74/root/usr/share/pear') in /home/easttexasnews/public_html/j4dev/plugins/content/cjforum/cjforum.php on line 19

How can I remove this extension.
