The error is here. When I save the changes it shows the page not found error. http://whmcs.website.com/admin/configgeneral.php?action=save

[WHMCS ChrisD]

@JOW Have you followed the steps outlined at https://help.whmcs.com/m/troubleshooting/l/1007451-troubleshooting-a-404-page-not-found-error-in-the-admin-area ?

[JOW]

Thank you for reply.

Yes I did, even remove and installed many times and checked different ways and applied all troubleshooting tips but again I'm in the same stage!

Have you removed all third party addons and added in a new copy of the /vendor, /admin & includes directories?

Do you get any errors with Google Chrome Developer Console opened

Yes, the same issue. 

 

 

[WHMCS ChrisD]

@JOW If this is a new install it could indicate an issue with the system cofniguration, what is your enviroment?

What errors shows in Help > Check System Health.

What errors can you see in the Google Developer Console?

You meant Google Chrome? 

 

[WHMCS ChrisD]

Hmm ok, could you try renaming your .htaccess to htaccess.txt and try saving just trying to rule out possible issues

 

[JOW]

I did it many time but it issue the "configgeneral.php" permission error. 

Quote

Forbidden

You don't have permission to access /mod/configgeneral.php on this server.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

 

[WHMCS ChrisD]

What are the permissions you have set on configgeneral.php?

[JOW]

The default permission is 644. But I've changed to 777 and it does't work again. 

 

 

[JOW]

This is the infrastructure of my domain: 

Domain: webiste.com = WordPress installed.

Sub-domain: cloud.website.com = WHMCS installed. 

[JOW]

Anything new? 

 

 

[WHMCS Sachin]

I will suggest renaming the htaccess file present in the Wordpress directory to htaccess.txt and disabling the Wordfence plugin in wordpress (if activated) and check if that resolves the issue. 

[JOW]

I did it before and test again but it doesn't work. I've disabled all WordPress plugins and changed the .htaccess file name.

Even I've removed Wordpress and installed the WHMCS once again and still the error is exist.

 

 

 

 

[WHMCS ChrisD]

Have you got WHMCS running on a subdirectory or Sub-folder e.g whmcs.mydomain.com or mydomain.com/whmcs

 

[JOW]

The first I've installed on a folder inside the Wordpress "site.com/whmcs" when I couldn't fixed this issue I decided to install it on a sub-domain. Now it is in a sub-domain " whmcs.site.com"

 

[WHMCS ChrisD]

Hmm ok and the same issue? It seems like there is a server specific issue causing this, are you running a cPanel server? Do you have a high enough PHP memory limit and  Execution time ?  MySQL Strict mode disabled?

[JOW]

SOLVED: It took me long time to fix it. This particular issue was caused by ModSecurity module. You can fix it by whitlisting the triggered rule. 

Thank you guys for helping 

[WHMCS ChrisD]

Glad to hear you got to the bottom of it @JOW ModSecurity can cause some issue from time to time so it's worth checking if you run into issues like this in the future.

Agradeço a todos por compartilhar como suas experiências, No meu caso eu preciso fazer algumas mudanças no whmcs,

eu fui em  Gerenciador de recursos e habilitação o ModSecurity depois abir o Cpanel e cliquei no "ModSecurity" e depois desativei temporariamente até eu eu fazer alteração necessária.
