I uninstalled the W3 Total Cache plugin and added the WP Super Cache; however, the second plugin didn’t get activated. I believe it was due to some W3 Total Cache files still showing on my blog and I went into FTP to remove them. Now I’m getting the below error message:
Warning: require(/wp-includes/load.php) [function.require]: failed to open
stream: No such file or directory in /wp-settings.php on line 21
Fatal error: require() [function.require]: Failed opening required
'/wp-includes/load.php' in /wp-settings.php on line 21
This may be a permission issue with those particular files. You may want to try resetting the permissions, or overwriting the files in wp-includes with those from a fresh install of the same WP version.
If you have uninstalled your wp-cache using the wordpress admin, you should also delete the wp-cache folders in your server under /wp-content/plugins/…[i forgot the folder name] that was auto generated by the plugin, and if still doesn’t work, try to delete your .htaccess file
The first time I upload WordPress to Server. I have the same issuse.
The problem because of I copy .htaccess from local to server
I fixed By change the url in .htaccess
