Getting display but with no wording/text in the Client front end
If you are not using the default english language. Make sure you had make a copy of the lang/english.php to the language you are using. For example, if you are using Chinese then copy lang/english.php → lang/chinese.php
Things to check when the module is not connecting to the remote server
If your module is having trouble connecting to the remote server, here is a checklist for you to verify everything is setup correctly
Click on the Connection Tester on the Server Listing in the Admin Backend. This will reveal whether your WHMCS server can make a http/https connection to your remote server's hostname. To test this on your browser, you should be able to goto http://yourhostname/CSFUnblockremote.php
, if it display a white page. Then the remote files are installed properly. If you are getting a 404, then the files are missing in the document root. If you are getting 500 then the permission and ownership is most likely incorrect.
Make sure the remote server module files are in the document root for the hostname of your remote server. For example, with cPanel/DA servers the default document root is /var/www/html. So perform a ls -lah /var/www/html and see if the remote server module files had been installed to that path correctly if using the auto installer.
Check if there is any PHP error_log in the document root and the directory above it. In a cPanel/DA server, it would be /var/www/ or /var/www/html
Check if the remote server have the proper ioncube loader installed for the PHP. For servers with multiple PHP installed check which PHP binary is being run when the remote server file is being run and during the cronjob
Is the cronjob setup for on the remote server. The cronjob is essential as it will self heal any permission or ownership change. Also make sure the cronjob is running using root
Remote server passes the connection test but blank rules
If the remote server's Web Address is set to use https, try set it back to http.
Module stop connecting to remote server
There are numerous factors on why the connection stop working. Here are a few things to check.
The module allows for a 15 minutes padding between server's time. So make sure the time between servers are in sync to the actual time
The remote server isn't blocking the IP of the WHMCS server
The module files on the remote server is accessible. Check the httpd logs and see if CSFUnblockremote.php is being hit by the WHMCS module
The ioncube loader updated during a update. Make sure the loader is able to decode the remote server files
Dealing with Multiple PHP server environments
The module auto installer will install the cronjob using the native PHP (/usr/bin/php). There are few things you need to watch out for when you have multiple PHP installed on a system
The PHP being run in the web root have ioncube 10 enabled
The cronjob being run have ioncube 10 enabled
For the cronjob, you can make any necessary changes to the PHP binary you desire to run as long as ioncube 10 is included.
IP isnt being removed from IPtables even though the IP removal was success via module
Try running the following command on the remote server
perl /etc/csf/csf.pl -r
and if you get result similar to
Can't locate YAML/Tiny.pm in @INC (@INC contains: /usr/local/csf/lib /usr/local/cpanel /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/csf/lib/ConfigServer/CloudFlare.pm line 41.
Compilation failed in require at /etc/csf/csf.pl line 202.
then you just need to run the following command to fix the missing dependency.
If you don't get the error when running the first command, then make sure there is a CRONJOB installed on the remote server.
