WordPress Blank Page Super cache Plugin problem Solved

Here is one of my horror story of blog migration which happened after I migrated Shoutmeloud to Knownhost. Migration was perfect but somehow Super cache WordPresswordpress_logo plugin did not like  my breakup with previous host and so he started acting weird. When ever I click on clear cache my wordpress dashboard goes blank along with whole site. There is no error and no kind of warning. Its so hard to diagnose such problem when you don’t see any kind of error on your pages. In my case my website become invisible to me.

In my case fault was because of Super cache wordpress plugin but this wordpress blank problem issue can be because of many problem.

Since I was not aware of what the problem is, so I started rolling back things. Last thing which I did was cleaning the cache so I had to rollback the super cache plugin. I logged into my server FTP and deleted the super cache plugin but it didn’t worked. My 2 cents , when ever you feel problem is big, start form scratch. I opened wp-config file and to cross check if all the database information is intact or if there is any blank space in it.

In my wp-config file I can clearly see this code

define('WP_CACHE', true); //Added by WP-Cache Manager

Since I have already uninstalled the super cache  plugin, I removed this line and re uploaded the file and everything worked fine. I installed the Super cache plugin and horror story started again. As soon as I enabled plugin, website went down again. I wish if I can share my emotions here.  After spending lots of time (5 minutes ) on Google search  and wordpress support forum, I realize I have to reinstall the plugin. That means uninstalling the plugin and reinstall the plugin again.

By uninstalling it means a complete removal of super cache plugin and  removing every instance of it. I took the help of notes provided by super cache plugin on how to uninstall Super cache plugin . Followed the steps and reinstalled the plugin and every thing worked fine.

Probably change in directory path while migration disrupt Super cache plugin. I hope this guide will help any one  who may get into such problem.

    On my test server, I came to a blank page so I decided to run chown and chmod on all files in the webroot. An error came back on files from the /wp-content/cache/supercache since I wasn’t using sudo. Not a solution but it lead me to a clue of supercache. I knew then to look for supercache problems and your solution was the first on Google.

    Thanks a lot!

    Did migrating affect any other aspects of your blog (i.e. traffic, rank, etc)? In any case, thanks for the info.

    I just went through the phase and now am relieved. I just replaced the corrupt comment file with a new one.

    I have had this problem on a number of wordpress sites and it took a while to figure it out. In fact, the supercache plugin stores information in it’s folder under wp-content/plugins. This means that you really have to start from scratch if you change something. Most plugins don’t do that, they only store things in a number of tables in the database. Especially if you start a site and add all the collected plugins by copying the plugins folder from another site, watch out, you’ll have this problem. Always start supercache clean. At least, that was what I learned… Apart from all this, I still like the supercache a lot!
