Hello,
I create normally a category and i put it in the top menu, then in sidebar and then again, for testing in the footer. My category doesn’t work. It shows http 500 error. here the log:
[28-Dec-2016 22:54:24 UTC] PHP Fatal error: require(): Failed opening required ‘/home/redlplzu/public_html/wp-content/themes/optimal/wp-blog-header.php’ (include_path=’.:/opt/alt/php56/usr/share/pear:/opt/alt/php56/usr/share/php’) in /home/redlplzu/public_html/wp-content/themes/optimal/index.php on line 17
So i probably missing a wp-content/themes/optimal/wp-blog-header.php file but i don t have it, neither in the backup, neither in the original Optimal theme.
The blog is: http://vaidiskate.com/
What can i do? Cheers, Paolo
