hi, after succesfull admin login, in page preview there is page error https://i.imgur.com/HP0eco9.png
(An error occurred while connecting to kourtakis-lighting.gr.
Please contact the website owners to inform them about this problem.)
If you just visit kourtakis-lighting.gr there is no problem, but if on the same browser you login as admin then the above error appears.
I have tried cleaning cache and on other browsers but the issue persists.
P.S you have credentials given on other tickets
