By default, pages from https are saved into -https.html, a different file. Since you have not provided more data, I guess you have edited your .htaccess manually and made it wrong, made it serve same http file over https. That would not be a big, that’s on you.

You have to provide more details on how devs should reproduce it. It won’t be fixed otherwise.

1. if you activated WPSC log, you probably only see WPSC output there. If you see notices from other plugins, you are probably looking at wrong log.
2. Debug it. It may be for a lot of reasons. Files access rights, messed with wp actions/filters, bad config, data you provided is insufficient to say.

You should not see any improvement in gtmetrix. WPSC does other things. Since you don’t know what they are – you obviously don’t need it.

Even though sauravs advice is arguable, in your case it’s good advice: WPFC may indeed improve metrics you are looking at, because WPFC can olso minimize scripts, adds expire headers, etc. It will suit you more than WPSC.

Yes, it is possible.

By the way I once lost WPSC settings, I guess something went wrong while opening “clear cache” tab in plugin settings, so using it with admin bar is not only convenient, but safer.

Have you tried pressing Regeneriere Cache-Statistik?
Also, look at your settings. Maybe you are using recommended “logged in user no cache”, and you never try to open site as anonymous – then of course you will have no cache, etc.

It works well with php7, no errors, no notices.

WPSC works pretty well, if it’s broken – you did something wrong. Easiest way to make it work again = start from scratch, add it again, it will work. You will probably have to follow faq and readme instructions.

If this is not something you like to do, you may try alternative called WPFC (fastest cache), which is inferior to WPSC, but have a record of working pretty well for those who do not wish to invest time in hacking.

Yep, understanding is a good idea.

WPSC makes your server give result to client faster. That’s it. That’s very important.
What you see in pagespeed score are other criterias, which are important as well, but has nothing to do with WPSC. There’s nothing wrong with WPSC.

If I understood Faq right, you may set donotcache constant in your frontpage template. There are other ways for sure as well, don’t give up ??

You can set it in your server config (apache, nginx) by static file’s mime type. You don’t need a php plugin for that.

Of course. It can be achieved in many different ways, both with wpsc default functional, and with external scripts.

For mod_rewrite start looking in htaccess. It checks “profile” and agent strings. There’s probably more, but I don’t know. The source is actually small, if you can reproduce your bug, you will be able to trace it in less than an hour.

My site have custom mod rewrites and code to store and serve ONLY .gz files. Gt metrix works fine, just like everything else.

You probably don’t have proper htaccess in cache folder. Something along this line. Try examining you response headers, content.

If you use modern mod_rewrite cache (dont know about php), urls will map to files paths 1-to-1. If nothing else, you will be able to just remove them by path.

How do you know it stopped working? Just trust some 3rd party service, or you made some other checks?

Google page speed have nothing to do with type of cashing wpsc provides. Believe real facts.
