The cache files are stored uncompressed when you use the mfunc stuff, as PHP needs to execute the code in the cache file, and it can’t do that if it’s compressed! * I may see if compressing the output on the fly is worth it. It will take up CPU cycles on each request but will save bandwidth. * Thread Starter [teamplaylotto](https://wordpress.org/support/users/teamplaylotto/) * (@teamplaylotto) * [15 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-dynamic-function-code-mfunc-breaks-the-site/#post-1549155) * that was it!! * I was kinda wondering how it would be able to see the dynamic function and execute it if the file was already compressed. * It works just dandy after I edited php.ini to have zlib.output_compression = On, it caches the page and the function stays dynamic (I tested it with `echo date('H i s',time());` in a function and I can see from the headers that the page is gzipped and the time shown within `` tags is up to date and the time shown from the call to the function below the tags shows the time when it was cached. * I am happy.

I expect that might make choosing a cache file problematic if it’s time was different to the server.. * Switching off ‘dont cache files for logged on users’ seems to make things work so maybe I should be thankful for small mercies (although the geek in me cant stand not knowing why!) * thanks Donncha * Thread Starter [teamplaylotto](https://wordpress.org/support/users/teamplaylotto/) * (@teamplaylotto) * [15 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-dynamic-function-code-mfunc-breaks-the-site/#post-1549215) * another update. * It seems the super cache plugin has an issue related to cookies. * It wont work for a brand new visitor. They need to have a cookie set for mfunc to execute the dynamic function. * I just tried on a new pc that hadn’t visited my site before and the mfunc enclosed function did not run. I logged in and then logged out and the function showed the output like it was supposed to. * after clearing cookies on the machine, the function does not show any output at all. * Thread Starter [teamplaylotto](https://wordpress.org/support/users/teamplaylotto/) * (@teamplaylotto) * [15 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-dynamic-function-code-mfunc-breaks-the-site/#post-1549217) * sorry to keep posting here but I’ve a way for you or anyone to replicate this cookie problem.. * visit [http://comluv.com](http://comluv.com) and see the entries in the footer area about the mfunc enclosed time and template time. * if you’ve never been there before (or if you have, clear cookies), you’ll only see one for the template time but, if you leave a comment then you get a cookie saved to your pc and then any page views will show both the mfunc enclosed time and the template time. * I think this might make it a bit easier to find the bug that is causing the issue.. * Thread Starter [teamplaylotto](https://wordpress.org/support/users/teamplaylotto/) * (@teamplaylotto) * [15 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-dynamic-function-code-mfunc-breaks-the-site/#post-1549218) * here’s a dump of the log file , I broke it up into 4 steps * [view page with cleared history] * > 20:33:57 /newsletter/ads-credits-donations-and-more-for-comluv-in-june/comment- > page-1/ No wp-cache file exists.

Even worse, if they didn’t have a cookie set by the site, they wouldn’t see the ads at all because the function wouldn’t run, it would get echo’d out to the page as text. * never mind, the site speed seems to be ok without it. If speed becomes an issue, I’ll look into it again. * thanks for helping * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 11 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-dynamic-function-code-mfunc-breaks-the-site/#post-1549240) * The best way to rotate those ads and serve them to anonymous users is by using Javascript, just like Google Adsense does. They work just fine on completely static html pages.
