As recommended for security purposes, I moved the 3 777 folders out of the public folder (in my case "httpsdocs" w/ my Plesk VPS). I set the path variables in configuration.php absolutely as follows:
$templates_compiledir = "/var/www/vhosts/mysite.com/whmcs_hidden/templates_c/";
$attachments_dir = "/var/www/vhosts/mysite.com/whmcs_hidden/attachments/";
$downloads_dir = "/var/www/vhosts/mysite.com/whmcs_hidden/downloads/";
For reference sake, WHMCS is located here (with the publicly-accessible bolded):
/var/www/vhosts/mysite.com/httpsdocs/whmcs
However, the screen is blank and I keep getting the following error:
Smarty Error: the $compile_dir '/var/www/vhosts/mysite.com/whmcs_hidden/templates_c/' does not exist, or is not a directory.
I know for a fact that the folder both exists and is a directory. I've experimented with folder ownership and confirming no open_basedir restrictions etc., but still no effect.
Can someone with Plesk knowledge/experience PLEASE give me some direction and guidance? I already opened a ticket and that got me nowhere.
Thanks,
Joe
