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.
