В описании к полю addtocart неверно указан shortcode. Правильный: [qfminicart].

В плагине два шорткода, по правде говоря, я не помню что делал третий. Возможно хотел, но не закончил. Для вывода корзины нужно использовать [qfminicart]. Сейчас нет под рукой сайтов на Вордпресс, постараюсь посмотреть вечером, напишу позже.

Этот шорткод выводит ссылку, по клику на которой открывается корзина в модальном окне. Вы, насколько я понял, хотите вывести содержимое корзины сразу на страницу. Это очень сложно будет сделать, корзина работает на ajax, то есть, на javascript. Соответственно, вам понадобится его (javascript) переписывать под DOM страницы. Сейчас он сделан под контейнер модального окна.

Отлично.

Проверьте в админке где именно у вас вставлен Shortcode. И проверьте html, возможно где-то незакрытые теги. Подробнее нужно смотреть на месте через админку, потому что причин может быть много, гадать можно долго.

Maybe it is. But without seeing the whole picture, nothing can be said. Sometimes, in such cases, it is easier to write the required functionality yourself “from scratch”. This can often take less time than picking at someone else’s code.

Then someone needs to look at the code of your site and this code. This is the only way to understand how it was integrated.

Also, what you have is all the code or just the base classes? You probably don’t have the functions that these classes run on pages.

What is this code supposed to do? Did it already work on WP or did it have nothing to do with it?

The laptop has nothing to do with it. This is probably some plugin that changes the url for itself. Or incorrect local server settings.

If you put your site on any test hosting, I can look at it and find out what it is.

I’m sorry, but working with the plugin involves some initial preparation. I can’t tell you how to change the text color. Perhaps if you have a question on js or php, or you will develop a complex form with difficult math and a complex interface, then I will give you help.
But now you are asking as a person who first encountered a webinteface. Perhaps you should look for a simpler solution. This plugin is for professionals.

If you want to make the design what you need, then css is necessary. Now you can do the following.

Open the project settings and create a css file, such as “slider.css”. Leave the copy styles checkbox enabled. Then, in the /wp-content/plugins/quickform/site/assets/css/slider.css file, find line 604 like this: .qf3form.slider .qfslider .slider_chosen.
Add this style:

white-space: nowrap;

If this is difficult, you need to ask for help. You can’t change the design without css knowledge.

What did you add to the math parameter of the field?, please tell me. If you want to show 3%, then add v*3/100.

If you want to swap the fields, just drag them in the admin panel. They are dragged with the mouse. Then click save.

Unfortunately, I can’t tell you how to work with Elementor. I don’t use it.
To demonstrate the screenshot, upload it to any file storage, then show the link here.

Yes. Open the page with the list of projects. In the right part there will be shortcodes in the table.

Unfortunately, my answers here are published with a delay. I hope the moderators will fix this and I will be able to respond promptly. Big apologies.

Good. Unfortunately, I don’t see an option to attach a screenshot here. I’ll try without it.

Click on the settings of this field, you will see a window with two tabs on the left side. These will be params and calculator. Open the calculator and insert the value there.
