Hi Jack,
I was actually just going to raise a ticket with you incase it was something to do with the slick-host theme, I did just upload the latest version you have for WHMCS v7.1
I previously had error checking on and had these errors, but now when I switch on error checking I do not get any errors displaying.
Warning: Parameter 2 to override_tpl_output_filter() expected to be a reference, value given in /home/<removed>/public_html/client/vendor/smarty/smarty/libs/sysplugins/smarty_internal_runtime_filterhandler.php on line 63

I will check server logs to see if I can find anything.
Thanks
