All WordPress core files had a wrong file directory like this. So I am facing the below error on wordpress admin panel
Error
wp-blog-header.php
Warning: Use of undefined constant ABSPATH – assumed ‘ABSPATH’ (this will throw an Error in a future version of PHP) in E:xampphtdocsdcidigital_blogwp-adminindex.php on line 13
Warning: require_once(ABSPATHwp-admin/includes/dashboard.php): failed to open stream: No such file or directory in E:xampphtdocsdcidigital_blogwp-adminindex.php on line 13
Fatal error: require_once(): Failed opening required ‘ABSPATHwp-admin/includes/dashboard.php’ (include_path=’E:xamppphpPEAR’) in E:xampphtdocsdcidigital_blogwp-adminindex.php on line 13
All core file had like this
require_once( dirname( __FILE__ ) . '/admin.php' );
Please check and give me some solutions
