In the last few months, [GAS] has gone down on occasions, mainly because of plugins problems. The one at the top of this list is the WP-Cache plugin for WordPress.
Strangely, this problem has only started about 4 or 5 months ago, when I decided to upgrade my installation of WordPress to a new build. At first, the problem was only occurring about once a month, but lately, things have really been starting to get out of control.
If your site is running the WP-Cache module and one day, you found your front page unavailable, try to access your WP-Login page. If it still loads, you’ll probably have found your culprit.
When this happens, the only way to get your site back up is to login to your dashboard, go to the WP-Cache section of the option menu and disable the plugin. When this is done, try to access your front page again. Does it load? If so, you can choose to keep the cache module disabled or follow the following steps to make it functional again:
- Login to your WordPress Dashboard
- Head over to Option -> WP-Cache
- Click on the “Disable it” button
- Click on the “Clear Cache” button
- Login to your site via FTP and head over to your “/wp-content/cache” directory
- Delete the wp_cache_mutex.lock file
- Go back to your Dashboard and re-enable the plugin.
Voilà, your site should now be back online. Please note that if the problem happened once, it will probably happen again.
