Hi,
I've just upgraded from 5.3.14 to 6.1.1 via a full release install.
Most things seem to be working fine, and I've switched to the six theme to minimise issues, however the domain checker doesn't seem to be working (not the domain spinner - standard checker). I've also switched to standard cart for the order form.
Every time you search for a domain it whirs for a minute or two and then just grinds to a halt and re-requests the captcha.
I've checked the error log and can see messages saying:
File does not exist: <redacted>/public_html/clients/includes/jscript, referer: https://www.<redacted>.com/clients/domainchecker.php
Has anyone else encountered this issue, and more importantly solved it?
