Symptoms
After an account transfer from one cPanel server to another, on rare occasions, the account's site doesn't load.
Description
If the site doesn't load and the Apache logs are checked using the following
tail -0f /var/log/apache2/error_log
while refreshing the website the following may be seen.
script not found or unable to stat: /usr/local/cpanel/cgi-sys/ea-phpXX
The XX in ea-phpXX is the PHP version. Example, ea-php74 is for PHP 7.4.
Workaround
If this occurs change the PHP version to another PHP version and then change it back to what was originally set.
This can be accomplished using MultiPHP Manager in WHM or cPanel.
