hi took me a few months but i’ve added you. i’ve disabled themes, plugins, wp-rocket, cloudflare and had to enable them again. But this keeps coming up:
Pattern attribute value ^[A-Za-z ‘-]{2,}$ is not a valid regular expression: Uncaught SyntaxError: Invalid regular expression: /^[A-Za-z ‘-]{2,}$/v: Invalid character in character class

Hi there, any joy with this issue? Our hosting provider won’t let us revert back to PHP 7.4 – where the plugin worked seamlessly. We have just renewed the subscription but am worried we are going to have to find another plugin? Please advise asap
Hi Lindsay,
Thanks for sharing the detailed steps you’ve already tried – that’s really helpful. From the error message you mentioned, it looks like the issue might be related to a regex pattern that isn’t being handled well with PHP 8.0.
So in order to help you out, could you please do one of the following so we can better investigate:
- Share a short video (screen recording) of the steps you take and the error that appears.
- Or, reach out to us directly via our helpdesk at helpdesk@wisdmlabs.com with the details.
That way, our team can take a closer look and guide you with a fix so you can continue using the plugin smoothly on PHP 8+.
Looking forward to your update so we can resolve this quickly for you.

hi thought i would update you. So in our form – the name field gives this error:
Pattern attribute value ^([^0-9@#$%^&()+{}:;\//”<>,.?~]*)$ is not a valid regular expression: Uncaught SyntaxError: Invalid regular expression: /^([^0-9@#$%^&*()+{}:;\//"<>,.?*~]*)$/v: Invalid character in character class
And when I put phone number in it gives this error:
jquery.validate.min.js?ver=1755785331:4 Uncaught TypeError: Cannot read properties of undefined (reading ‘isValidNumber’). Exception occurred when checking element field_Phone_1599135488499, check the ‘validatePhone’ method.

Chatgpt suggested a temp fix:
public function offsetGet(mixed $offset): mixed
{
return isset($this->container[$offset]) ? $this->container[$offset] : null;
}
But it didn’t work. The form still “submits” and is redirected to our thank you page. BUT there is no product info now being recorded in the enquiry (0 item) – same if I use your default form.
We need to get this sorted out quite urgently and I have sent you access. Would really appreciate it if you could fix it as soon as you can 🙂
Thanks so much
