Your site is on localhost? Have you configured the mail server correctly on it?

At the moment, I can’t say the reason. This may be related to your URL settings or your local server settings. If this happens again and the admin lets me see the site, then I can add immunity to the plugin. But nothing can be done yet.

It’s hard to advise you without seeing the files. Check for the file /wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php. But it is better to re-download it from the fresh WordPress distribution of the same version. See it in the file /wp-includes/version.php.

If this doesn’t help, change everything except the wp-content folder and the file wp-config.php. But be sure to make a backup before that.

If even this doesn’t help, change the theme via phpmyadmin or FTP.

You can try the last paragraph first.

If you have FTP access, you can restore access to the site’s administrative panel. Then, if the admin panel works, just update WordPress. This can help in some cases.
If not, then a specialist needs to work with your files, find the problem and fix it. This can take anywhere from two hours to a whole day.

You have a file jquery.min.js loaded with the defer attribute. Therefore, all scripts that use jquery must be inside:

window.onload = function(){
}

Oh, that’s easy. Create a form project with the default calculator type. Save project and create a group of fields. Put two fields there: calculatorSum and qf_range. In the qf_range field in the math parameter, insert v. This will mean the value of the field. Save and publish the form to the page.

Use the settings of your fields to customize them. Use the customHtml field and the css file to get the design you need.

You will get the same thing as in the example shown. After that, you will be able to change the calculator as you need. I can help with that if there are more pointed questions. It will be very good if I can see what you are doing on the site.

You can try resetting the cache in your browser. If this doesn’t help, see javascript errors in the browser console. I looked at your site in Google Chrome and didn’t see a problem.

Hello, wpusr1. Is this error only displayed in the QuickForm plugin? Your site is on localhost? I want to look at your site and find out the reason, if possible. I’m interested in that. So far, I haven’t been able to get something similar on the sites available to me.

It’s not very clear what you want to get. Do you have a calculator? In this case, look at QuickForm, the new plugin. You can easily make any one. Or write your problem in more detail.

You can use @media screen. Add this to the css file.

@media screen and (max-width:720px) {
.wp-block-image img {
width: 150px;
}
}

Do you really need a multiselect? Do this with a few checkboxes. It will be more convenient and more beautiful, because the checkboxes are easier to customize.

Go to the file /wp-config.php Search and change the lines as here

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );

Then look in the file /wp-content/debug.log your errors.

The slide-anything plugin doesn’t work properly. You have an image in a slide with a height of 60400px.

Go to the repository. Install the cool QuickForm plugin. Make a cool calculator using your own formulas. This can be a bit tricky if you are a beginner. But you will have help in this case.

echo is triggered out of sight, because after the function is running, a redirect occurs.
