Hello - absolutely dumb-founded by this random error-code that has appeared after no major alterations to the site
It can be found here
The error reads:
Notice: Trying to get property of non-object in /hermes/bosoraweb073/b2912/nf.olivernat/public_html/e-ternity/wp-includes/nav-menu.php on line 591
Any ideas would b e greatly appreciated - could not find any solutions to similar issues online - and very limited similar issues were even out there!
