I setup a website for my uncle a while ago. He has been updating pages but thats it. Now when he tries to access his admin area he gets
Warning: Illegal string offset 'order' in /home/WEBSITE/public_html/wp-content/themes/diverso/core/functions-core.php on line 19
Warning: Cannot modify header information - headers already sent by (output started at /home/WEBSITE/public_html/wp-content/themes/diverso/core/functions-core.php:19) in /home/WEBSITE/public_html/wp-includes/pluggable.php on line 899
He says he hasn't updated anything.
I have looked in other topics which says to make sure there isn't any blank lines etc. but the files seem fine.
Please help. Thanks
