Hello,

When in backend I go to hikashop -> orders and I do a research I get error 1054.
When I then click on "return to control panel" I come to the control panel. When I then go to hikashop -> orders I do not see my orders but again the error page.
When I logout from Joomla and login again and go to hikashop->orders I can see my orders again.

When I do a similar research on hikashop->customers everything works fine.

I already did "check database" but the problem remains.

Do have an idea why the search function on my orders does not work ?

Thank you very much for your answer,
Mireille
