[SOLVED] Please help me remove a code that slows down the speed.

Hello.
Please help.
For several days my site has been working extremely slowly.
I found the problem:
a script has been added to the pages

<!--Start Cookie Script--> <script type="text/javascript" charset="UTF-8" src="https://chs03.cookie-script.com/s/f0dc6 ... "></script> <!--End Cookie Script-->

It is located at the end of each page: home, product, cart, payment.

The end of the code looks like this:

<p class="pull-left">Powered By <a href="http://www.opencart.com">OpenCart</a><br /> E-Parker.bg &copy; 2025</p><p class="pull-right">OpenCart Theme By <a href="https://goo.gl/NKXdWy">HarnishDesign</a></p>
</div>
</footer>

<!--Start Cookie Script--> <script type="text/javascript" charset="UTF-8" src="https://chs03.cookie-script.com/s/f0dc6 ... "></script> <!--End Cookie Script-->
</body></html>

Since I can't contact the person who placed it. Please tell me the place (file) from where I can remove it.

Thank you very much.

footer.twig

Either manual with an editor or edit it with the already integrated template editor in the backend.

Check in catalog/view/theme/default/template/common/footer.twig and the same file in your theme.

Disable and refresh modifications one by one until it's gone.

Guess it comes from the theme ..
So, when he disables it, it should also be gone .. but then he has no custom theme anymore ..

Your web theme is from Harnish Design, please double check with this theme author as to whether this so-called cookie script should even be in there at all (maybe your server has been compromised!), and if so, why it has to call an external server to get the javascript file instead of having it locally stored on your own server. The external server appears to be non-responsive.

Give us a link to your site?

Hello,
I tried all the advice.
I found
catalog/view/theme/default/template/common/footer.twig
there was a script, I removed it.
But nothing on the site changed.
In the files I found 3 more footer.twig and there was the harmful script, I removed it, nothing changed.

Disable and refresh modifications one by one until it's gone. I did it but it didn't help.

My site is: https://e-parker.bg/index.php?route=common/home

<p class="pull-left">Powered By <a href="http://www.opencart.com">OpenCart</a><br /> E-Parker.bg &copy; 2025</p><p class="pull-right">OpenCart Theme By <a href="https://goo.gl/NKXdWy">HarnishDesign</a></p>
</div>
</footer>

I wonder if it could be somewhere else.
Given that it is located after
</footer>

Did you refresh the theme cache after removing it? It's the blue cog button on the dashboard.

Has the script appeared back in the footer.twig file once remove or was it just appearing on your site?

Thank you very much everyone.
I did everything, finally cleared the cache and the site is fine.
Once again, thank you very much.
