Hi @serverhosh,

The error is caused by out-dated custom template files.

Please make sure you've consumed the template changes between the old version and 7.10.2. The diffs are published in the release notes: https://docs.whmcs.com/Version_7.10.0_Release_Notes#Template_Changes

As an immediate workaround you can switch to the stock "Six" template via Setup > General Settings > General tab

We changed to SIX but still same issue.

@serverhosh it may be best to open a support ticket via www.whmcs.com/submit-a-ticket or www.whmcs.com/reseller-support

It is crazy that every time a template is updated we have to re-apply our customisations.

Wouldn't it be a novel idea for WHMCS to have child templates like most other software does?    That would solve this problem for all of us once and for all.

Curious, I just checked the changelog for Six template from 7.9.2 to 7.10.2 and it shows

Quote

23 files changed with 817 additions and 232 deletions

To expect us to update our customisations when such a huge number of changes are made is crazy.

Hi @123host,

We appreciate that manually processing changes could be time-consuming, which is why we publish them to GitHub. Using git will enable you to consume template changes in minutes once setup.

Check out this blog post for the info: https://blog.whmcs.com/112975/customising-templates-the-easy-way

@WHMCS John I followed the link.  In the blog article there is an example

Copy & Paste: git clone git@github.com:WHMCS/templates-six.git my-hosting-company

but it fails

# git clone git@github.com:WHMCS/templates-six.git whmcsfiles
