You write, that you are using WHMCS v7. But the admin page shows a WHMCS v8 installation. 

The exception contains the word "Forbidden", so my first thought would be a permission problem (wrong chmod / chown?). However, against this theory speaks that this problem would then probably not only occurs when creating customers. I have also found this knowledgebase entry from WHMCS, which also refers to a problem where the error message contains "Forbidden": https://help.whmcs.com/m/v80/l/1309724-troubleshooting-a-clientrequired-forbidden-error-when-deleting-quote-items

According your screenshot, you are not using the latest WHMCS version. I would therefore suggest to update your WHMCS installation. Maybe it's a WHMCS bug.

Beside of this, i suggest following:

• Remove the files at the /includes/hooks directory and retry it.
• Don't just recopy the WHMCS files, but delete WHMCS completely from your server and upload a fresh copy. This ensures that there are no leftovers.

About point 2: You could use "rsync --delete --dry-run" to check in advance what differences there are between the content on your server and the original data.

If all this does not help, you will have to contact the WHMCS support.
