Hi Saguaros,
Just came back from holidays, thus the delay before answering your question.
I installed the quickstart version and did very little editing. I have deactivated what few additional modules I had installed (only one actually, if I’m not mistaken), all for nothing : I still have the same error message.
Uncaught TypeError: Object #<HTMLDivElement> has no method 'reset'
I have tried commenting the offending line in /templates/ja_cloris/html/mod_jaquickcontact/default.php, but the error appears again as soon as I try to send a message :
Uncaught TypeError: Object #<HTMLDivElement> has no method 'submit'
Unfortunately, I am no JS expert…
