The only solution I found for this was to edit the files contained in templates/ja_onepage/html/mod_jaquickcontact
Look for
<form action=”#” name=”ja_quicks_contact” method=”post” id=”ja_quicks_contact” class=”form-validate”>
and replace
“#”
with the exact link to the contact form you are using on your menu.
In my case it would be
“#contact_us”
so it reads
<form action=”#contact_us” name=”ja_quicks_contact” method=”post” id=”ja_quicks_contact” class=”form-validate”>
In the demo version provided by JoomlArt it would be
#get_in_touch
When a wrong captcha code is entered, the page reloads but now it will take you down to the form, where the captcha error displays. I also changed font size for the error message, so it would be more visible.
I hope this helps you. I had tried to find a solution for a time until it occurred to me it would be as simple as that.
