Avtar976,
W3 Total Cache may have made changes to your .htaccess file and also, potentially, your wp-config.php file. I’d recommend:
- Backing both files up (maybe copy to htaccess.bak and wp-config.bak)
- Opening the original files and look for any special non-standard entries and remove them, or comment them out.
- Try to reload your dashboard and login
W3 Total Cache may have entries in your wp-config.php that look similar to this:
/** Enable W3 Total Cache */
define('WP_CACHE', true); // Added by W3 Total Cache
// Enable the WordPress Object Cache:
define(ENABLE_CACHE, true);
I’d comment the define lines out by prefacing them with a //.
W3 Total Cache may have also added lines to your .htaccess similar to this:
# BEGIN W3 Total Cache
<IfModule mod_setenvif.c>
SetEnvIfNoCase Accept-Encoding (gzip) APPEND_EXT=.$1
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} \/$
RewriteCond %{REQUEST_URI} !(\/wp-admin\/|\/xmlrpc.php|\/wp-(app|cron|login|register).php|feed|wp-.*\.php|index\.php) [OR]
RewriteCond %{REQUEST_URI} (wp-comments-popup\.php|wp-links-opml\.php|wp-locations\.php) [NC]
RewriteCond %{REQUEST_METHOD} !=POST
RewriteCond %{QUERY_STRING} =""
RewriteCond %{HTTP_COOKIE} !(comment_author|wp-postpass|wordpress_\[a-f0-9\]\+|wordpress_logged_in) [NC]
RewriteCond %{HTTP_USER_AGENT} !(bot|ia_archive|slurp|crawl|spider) [NC]
RewriteCond /var/www/html/finance/cfodailynews/wp-content/w3tc/pgcache/$1/_default_.html%{ENV:APPEND_EXT} -f
RewriteRule (.*) wp-content/w3tc/pgcache/$1/_default_.html%{ENV:APPEND_EXT} [L]
</IfModule>
# END W3 Total Cache
I’d remove all of this stuff during troubleshooting and leave only:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
You might also try (if you haven’t already) deactivating all of your plugins. If you can’t login to WP, you can’t do it the traditional way, but if you can access files on your server, temporarily rename the wp-content/plugins directory to something different (I use wp-content/_plugins). Then reload the login and see if it helps.
Depending on your site’s settings, it’s possible you may also have something cached in your browser, so you might wish to clear history, try another browser, or use private browsing mode to test.
Good luck!
