Error in form in email box

I am getting this error when starting to type an email address in an email box. It is only thre at the start of typing but goes when the address is complete. It doesn't affect the form but does produce the message on screen.

Array to string conversion in \htdocs\Joomla\libraries\chrono_lib\widgets\fields\text.php on line 15

Any ideas  on how to remove please? Thanks.

Hi gnasho

Do you have any Event Triggers/Listeners set for this field ? if yes then what do you have ?

if no then another script on the page (from a different plugin) is listening to the field value change and does something which causes this.
