    After adding product in shoppingcart when clicking on previous page than it appears on the screen:

    ”CONFORM FORM SUBMISSION \, This webpage requires data that you entered earlier in order to be properly displayed. You can send this data again, but by doing so you will repeat any action this page previously performed. Press Reload to resend that data and display this page.

    Press the reload button to resubmit the data needed to load the page.
    ERR_CACHE_MISS

    This above mentioned notice is very rare one. I spent hours and hours but it couldnnt help. Just seeking your guidance in this regard.
    Thanks

    Hello,

    Do you have the same situation with a default theme?
    If this situation persists with our theme only, provide screenshots and links so we can reproduce it step by step.

    Lightshot Screenshot tool https://app.prntscr.com/en/index.html makes screenshots and generates links then you can provide links of screenshots here.

    Oppaa, solved. I uploaded insert header and footer plugin, and put this small javascript into footer and the magic started:

    <script>
    if ( window.history.replaceState ) {
      window.history.replaceState( null, null, window.location.href );
    }
    </script>

    Now just looking further how to increase page upload speed.

    Thanks for your quick reply. I didnt knew about that app which u snet but now i have downloaded it and will use in future like this. Above mentioned errors screenshot: https://prntscr.com/shyq8z

    In stead of downloading Ajax plugin, I just added those few short lines into my footer and problems solved.

    Thanks for your quick reply. It wasnt an easy job to replace a theme. it took almost a month to replace my website’s theme from techmarket to xstore. Maybe i had a bad designer, i dont know. Now i wouldnt dare easily to hire somebody again for speed optimization. So i am doing it for last one week here and there. I have uiploaded one by one almost all the cache plugiuns, changed the settings almost many many times of each plugin to get the upload speed better. But its not working. I have 50% paid traffic on my website, where the most important ius upload speed.
    * At this time i have 2 plugins working without conflicting (hummingbird and wp fastet cache). Thr is also an option to compress different files in hummingbird but i wouldnt dare to compress theme related scripts and other files and deactivated Asset optimisation because it keep compressing files automatically. That can break my theme.
    * top slider on mobile and other devices keep buffering for a very long time and thn appearing it. This is causing a high bounce rate too. The other product images are also appearing with some delay.

    Please can you have a look just one time if anything can be improved with these or those plugins, minifications, or compressions, if speed can improve and bouncerate can be reduced, everything is ok. I already took a backup. I will be very thankfull to you.

    Hello,

    Use Lazy loading for the sliders http://prntscr.com/sja2el
    Also, I found that you use 2 sliders for the desktop and mobile versions. Try to reduce them to 1 and use the Revolution slider responsive settings to make slider nice looking for both mobile and desktop.
    Besides both sliders do not include more than 1 slide. In this case it would be better to replace sliders by simple row with the image background and simple text with button inside the row. It will allow you to remove the slider scripts and speed up the site a little.
    Unfortunately, I can’t give you more suggestions because personal site optimization is outside the scope of our support and that’s why we don’t have personal optimization experts. You may contact our partners – WPKraken team to get help with the personal site optimization.

    Thank you, Somebody is going to work on these above mentioned issues in upcomming days.
    Maybe some theme related big files to compress, combine and adding to footer is also a solution? As today i buy a premium hummingbird plugin to speedup my website. Here is the screenshot with those files, which still can be configured with hummingbird to speedup my site as it is at the lowest point currently if i compare with previous speeds. https://prntscr.com/skccyg
    looking further for your guidance in this regard 🙂

    Hello,

    You can use cache plugins to minify, combine our styles and scripts. Our theme supports it.
    Also, we are working on improvements of the CSS structure of our theme http://prntscr.com/skilb7 https://www.8theme.com/roadmap/

    Dear,
    I have just a while updated my theme but i got blanked website https://prntscr.com/skqvgz . Please can you help me as i have many visitors, visiting my website. Basically i took a backup too before updating it. I checked mistakenly my theme after updating in normal chrome browser but not in incognoto. It was looking ok, so i deleted the backup.
    But later on when i checked in incognito, it was blanked.
    I hope it can be a minor error otherwise i have to force myself to upload one week old backup.
    Waiting for your quick reply, if possible.
