thanks

I agree in closing this issue. The 2 main points in it are definitely wrong.

1. You claim protostar to be the problem for slow page speed. Look at the results from my website (unfortunately in German, pagespeed decides about language), which is a pure protostar with a few overrides for colours, and you'll see they are fine. So it is maybe you as the admin of your website doing something wrong? Htaccess or PHP settings, whatever?
   

2. The checksum as URL parameter on assets (js, css) are common technology on today's websites, to make sure new versions will be applied regardless of older cached version. Just analyse markup of some big popular commercial or public services site and you will see.

P.S.: Or other popssible reason for 1st issue with page speed: Maybe you have hundreds of 3rd party plugins installed for this and that fancy purpose, that can also slow down your page ;-)

0 - 3rd party plugins installed , this is new site just default joomla

Richard you should test copy protostar name it mytemplatecopy and instead of this

you get this code in your website?

.../templates/mytemplatecopy/css/template.css?8e17160b713641b3cc489b29e3405a51" rel="stylesheet" />
.../templates/mytemplatecopy/css/user.css?8e17160b713641b3cc489b29e3405a51" rel="stylesheet" />

@Milglius Sure I get this code, and it is pretty fine for me, because this is modern technology standard. Google has no problems with it. When I change CSS, I don't have to clean browser cache to see the results, because the checksum will have changed so for the browser it is a new URL so browser doesn't use old cached stuff. Check markup of your gouvernment's website and I think with a likelyhood of 95% you should see they use this technology, too.

P.S.: It has nothing to do with copying the Porotstar template. You will get the same on the original Protostar.

@Milglius One more thing about the "strange" css URLs and SEO: You know every search engine has a cache, whe people can see the cached version of pages in the search results. Imagina what happens if you change content and css of your site so stuff gets indexed and cached again, but it still would use the old css from their cache? So in fact it was the search engines who have required this technology using a version-dependend URL for js and css assets. So why should it not be SEO- friendly?

Final comment before I ask for this to be locked

It is NOTHING to do with copying the template!!!

@brianteeman Thanks for confirming what I said above. Shall I lock it now?

@Milglius I will lock this conversation now. Everything related to your "issue" has been explained to you several times, and above you can read all. There is no need to continue with it, you just waste our time and keep us from catching and fixing the real bugs.
