Fatal error: Call to undefined function is_multisite() in /home/smsbusin/public_html/wp-includes/default-constants.php on line 20
Now i can't view my blog again nor login to my wordpress admin area
Please how can i resolve this issue?
Can low disk space cause something like this?
I have deactivated my plugin folder via the file manager in my cpanel to plugin_hold yet the issue was not resolved, i also renamed my theme to freshnews_old but no show. Please any help will be appreciated.
