Since some days I get the message by clicking the blue answer field:
An error occurred, operator can be used only with paginated fields or array
Unfortunately I cannot close the answer message, the blue answer field doesn't move. In despair I push or click many times the mouse, nothing reacting. But after leavin the website and beginning anew I see to my surprise that my answer is shown - many times, so that I have to delete them - exept for one. Who can explain the problem and what to do?
