WP Super Cache killed my site

I think you need to track down the specific problems on your site instead of blaming the plugin.

It was the plugin. You can verify this with a quick search for “WP Super Cache” and blank page or by simply reading the reviews of this plugin on the support forums, the flaws that come with this plugin are frankly undeniable.

It’s great that it’s working for you and the others. You just need to acknowledge the fact that it doesn’t work for just as many people, and in fact causes them serious issues on their blogs.

And you need to acknowledge the fact that if it works for one setup but not for another setup, then something is different between those two setups.

You can argue “it doesn’t work” all day, but the truth is that it’s not working for your particular server and setup. Until you acknowledge that, nothing will ever be fixed.

Without information on what exactly it is about your site that makes it not work, Donncha can’t possibly do anything to fix it. See how this works?

Esra – perhaps you can hire someone to help you debug the problem on your site.

Speed is very important and if you’re doing serious amounts of traffic I presume it’s monetized so you can hopefully afford to spend money on it.

monetized so you can hopefully afford to spend money on it.

We are in the Middle East, most of us do not monetize our blogs here. We use the Internet for human rights, and to practice our right to free speech which is punishable by death where we live. Not to make money.

We are tracking the Revolution in Iran and people come to our site as a primary source for on-the-ground information, this is why we value speed considering where our target audience is located and ever since we have installed this plugin the results have been nothing but disastrous.

I simply wish to find an alternative for people in the nonprofit field and therefore cannot afford to hire assistance. Unfortunately there seems to be none. I appreciate that this plugin is free, it’s just flawed.

this plugin has worked great for me for years until I upgraded today to v.0.95. Now when i try to go to my plugin page i get this error:

Fatal error: Call to undefined function wp_cache_user_agent_is_rejected() in /home/.myth/nedsferatu/blog.nedsferatu.com/wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 41

deleting the define cache true line from wp-config seems to fix it until i do something in the admin page like update status or clear the cache. this only affects my plugins.php page. any ideas? thanks so much!

agree with Esra…

i’m about to install this plugin until i read some review about this plugin…

it is very scarry to find out most of the reviews is more to negative than positive…

I think I won’t use this plugin at the moment… until it is confirm stable…

nedsferatu – try the development version. It should work better for you.

ssufian – considering the plugin is running on tens of thousands of sites I think it proves how good the plugin is that there are so few forum posts about it. If everyone was having problems this place would be inundated with requests. It is stable.

ah ha! brilliant! thanks Donncha keep up the great work.

Donncha, my blog source code said at the bottom that it was cached by WP cache and by SuperCache. The date and time were static so the message was correct. But in wp-content/advanced-cache.php there was an error that Super Cache is broken. I found that error, because my blog loads very slow, so I suspected that the plugin did not work. There is an instruction that I have to check if a certain path is correct. How to check that? HOW to repair the path and WHERE to repair it? Sorry, but I don’t understand it. Can you be more specific? Thanks!

Just delete advanced-cache.php and the plugin will regenerate it next time you load the admin page.

We had this running on a site and then when I upgraded my core WP install it gave me the White Screen of Death.

I found 2 causes of this; one not mentioned here.

1. The WP_CACHE = true value in the wp_config file. If WP Super Cache is misconfigured then this will kill your site. Delete this and it should be back up.
2. If the above didn’t work, check for a closing PHP ?> tag in your wp_config.php file along with white space at the end of it. If there’s white space at the end of your config file it’ll kill your site.

After deleting advanced-cache.php, wp-cache-config.php, the wp-super-cache folder, then installing from afresh, the plugin started working again with no problems.

Having Problem with the plugin

I have got the error 500, site is dead.

I had a 301 redirection like this:

Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^severus.es [nc]
rewriterule ^(.*)$ https://www.severus.es/$1
[r=301,nc]

I have tried to uninstall the plugin from the admin panel and the process stop in the middle showing this:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /mnt/web8/20/59/51979159/htdocs/wp-content/plugins/wp-super-cache/uninstall.php:6) in /mnt/web8/20/59/51979159/htdocs/wp-content/plugins/wordpress-paypal-shopping-cart/wp_shopping_cart.php on line 22
UNINSTALL_WPSUPERCACHE must be set to a non-blank value in uninstall.php

My config.php does not have the line WP_CACHE = true at all

So, now I am on the middle of nowhere and the site is dead.

The only idea was to rename the .htaccess to .htaccess1 and the site came back but just the home page. Any link is going to a 404 error page.

So any help would be appreciate

Sorry, it was duplicated

severus – there are docs in the readme about uninstalling.
