I am using Google's **mod\_page speed** with **Apache** on **Centos 5.X VPS** (I'm not 100% sure on the exact Centos version, but I know it's in the 5 series.)

I am hosting numerous WordPress websites with W3 Total Cache, all of which have the latest version of WordPress and W3TC installed.

Now, here's my issue. When editing any sort of "front-end" code (HTML, CSS, JS, ETC), it does not update after the page has been rendered for about 5 minutes.

I have cleared ALL W3TC caches and cleared browser caches. Normally in the past (before installing of Google's mod\_pagespeed) this would have cleared and updated instantly. Ever since installing mod\_pagespeed, I have ~5min delay (sometimes longer) of all front-end code updating (even after clearing caches).

I have heard running mod\_pagespeed on a VPS is a big NO-NO. Any feedback on this rumor?

I have also heard running mod\_pagespeed in combination with W3TC (W3 Total Cache -- WordPress plugin) is another big NO-NO. Any feedback on this?

**What is causing this issue?**

* Is it normal? Should I just ignore it & work around it?
* Is it because mod\_pagespeed is still buggy?
* Is it because I shouldn't be running mod\_pagespeed on a VPS?
* Is it because I shouldn't have BOTH mod\_pagespeed & W3TC installed?
(Are the conflicting?)

Or are all of the above irrelevant? Should I just make all of my changes on a local development server, then upload to the live server once final changes have been made?

mod\_pagespeed appears to run perfectly other than that annoying 5 minute delay on front-end code changes.

So many questions, with so little knowledge. If you know anything about this delay with mod\_pagespeed, please enlighten me with your thoughts on this particular situation.
