Recently I've had a lot of SQL errors on my server, due to XML sitemap.
So, I ran the debug mode and I found this:
'Warning: htmlspecialchars() expects parameter 1 to be string, array given in /home/[mysite]/public_html/wp-content/plugins/google-sitemap-generator/sitemap-ui.php on line 124'
Can you please advise on how to fix this?
Many thanks for your support!
