I usually prefer helping people publicly so that others can learn from mistakes or issues and apply it to their site.
Should you wish to post a segment of code (rather than the site), that's great.
My guess, the problem is with CSS, and in particular the ".a" variable in the style.css file.
On the flip side of things, if you're using a submit form, then you shouldn't be using a link on the button and instead it would be a POST request on the forum tag itself.
