Title: [Plugin: WP Super Cache] Why clear the cache? Last modified: August 19, 2016 --- # [Plugin: WP Super Cache] Why clear the cache? * [Drawer](https://wordpress.org/support/users/drawer/) * (@drawer) * [17 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-why-clear-the-cache/) * Hello, trying to understand all about this -read your main page and lots of questions posted here. * I see that index is on the do not cache list, even though it seems like it should be cached. I see that the warning in red that I am writable has not been fixed by many people, and 755 is ok. I have 2 questions left. It looks like I should enable compression, is that right? Calling my server to ask takes an hour. If it doesn’t much matter I’ll turn it off. Also: if creating the cache is the point( by me reading my own pages), why should or would I need to delete or clear it? I’ve seen that mentioned a bit here. * I look forward to understanding this better when you have the chance to reply!

And then the readers can see my cache, I believe. * I will have a small blog to start with – is once a week about right for me to clear and then re-cache my pages? * Forgot to ask another important question: will this also cache my own admin pages? On my first blog, 2.2, the admin pages are SO slow. I am just starting this new blog on 2.5, so hope it will be faster. * Thanks again for your prompt response. * [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [17 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-why-clear-the-cache/#post-789373) * There’s no need to go visiting your own site. Whatever pages are visited by anyone will be cached. Also, if you’re logged in, you’ll see a different page to an anonymous user. * No, it won’t cache your admin pages. Have you installed an object cache plugin?( use Google to find them) * Thread Starter [Drawer](https://wordpress.org/support/users/drawer/) * (@drawer) * [17 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-why-clear-the-cache/#post-789455) * I haven’t yet, donncha, but I’m reading them. * I finally installed Super Cache on my big blog last night, and all the Google Adsense ads today are PSAs or are in another language. I guess Adsense can’t read html, good for them. * I don’t see this problem listed, but have you come across this before, or have a solution? * Thanks again. * [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [17 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-why-clear-the-cache/#post-789457) * Drawer – I use wp-super-cache on all my blogs and haven’t seen that problem with Adsense. * Thread Starter [Drawer](https://wordpress.org/support/users/drawer/) * (@drawer) * [17 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-why-clear-the-cache/#post-789459) * You are right, donncha. * After more searching, this is an unusual problem. I’m using MistyLook, which I think is kind of a frame. I’m hoping that isn’t the problem. * I see that all my older posts, like a month ago, all show adsense fine. Just the newer ones that Super Cache saved, have bad Adsense, and are other languages and PSAs. * Also, when I look in my htaccess file, everything looks like your Mod Rewrite Rules. * But in wp-content/uploads, I noticed advanced-cache.php and wp-cache-config.php have permissions of 644, so I changed to 755. Could that have been the problem? Adsense takes at least a day or two to readjust itself, so I won’t know if that was it, or turn Super Cache back on until you have a chance to look at this. I’m also waiting for my server to call back, to check on the compression thing. * Thread Starter [Drawer](https://wordpress.org/support/users/drawer/) * (@drawer) * [17 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-why-clear-the-cache/#post-789472) * Donncha: I even called corporate for my server to help me figure this out, and a tech guy is trying SC on his own blog now. * Here is what I see inside the bowels of my infernally slow File Mgr on my server: I can see wp-content/cache/my cached posts fine. If I click on them, the page is ok, and adsense ads are ok. * However here is where Super Cache goes: my_blog/wp-content/cache/supercache/mywebsite. com/myblog/2008/04/13/name-of-my-post/index.html, and when I click on that I can see the post when I drill down – and I do mean drill-, but the adsense ads come up another language. Is this where super Cache is supposed to go? * All permissions are correct. Compression is disabled. Can you please help me, because I really want this to work! * Thanks!
