I have multiple WordPress websites. All of them have been running fine for a long time. But suddenly my WP websites shown the error:
This page isn’t working
When I investigate the problem I found this in the error log:
"Uncaught Error: Call to undefined function wp() in /home/nc136xrqx05i/public_html/wp-blog-header.php:16"
and the wp-load.php file is 0.
Then I rename the plugin files. Then the websites run but if I try to install a plugin from the plugin folder from dashbaord, wp-load file is becoming empty again and the site goes down.
How can I solve that?
