Thank you for that information. I was eventually able to replicate this locally after moving some things around and registering as a User. I have created a pull request based on @marcel112 original fix as this is indeed the correct resolution. MySQL's REGEXP() method interprets { as the start of repetition notation so we simply need to escape the character so it's seen as a literal squiggly bracket.
REGEXP()
{
Cheers.
