How to Fix "Elementor Widget Panel Not Loading"?

If your Elementor panel does not load properly and is at a constant loading mode, then these are the most common causes that are responsible for this error display as well as the best solutions on how to fix it. This can be usually due to an incompatibility with a certain plugin, due to a resource issue, or your server settings do not match with the values recommended. 

Most Common Causes and Solutions 

Below we will show you the most common causes that make the "Elementor Widget Panel Not Loading" error occur and all the best solutions you troubleshoot the issue. Please follow the steps carefully and make sure you are precautious before you make major changes to your website. We recommend you take a full backup of your WordPress website before you undergo major changes on your site. 

Check to see if you are running your website on the latest update

The first thing you should check is if you have updated to the latest version of the Neuron Core/Neuron Builder plugin (depending on your active Neuron theme). This might cause incompatibility if Neuron Core/Neuron Builder is running at an older version than Elementor.  

Make sure to check if you are running your website on the latest Elementor update, WordPress update as well as theme update. Often times it isn't obvious that there's an update. You should always check under the Update option from the WordPress Dashboard. Click on the Check Again button just to make sure there aren't any updates you need to take. 

Another precious step you can make is to check if there's a plugin conflict with Elementor. To do that, from the WordPress Dashboard > Plugins > Installed Plugins. Make sure to check a tick before every plugin you've installed on your WordPress website except for Elementor. Deactivate all plugins, except for Elementor. Check if the issue is resolved. If yes, activate all the plugins one by one until you find the culprit. Please contact the plugin's support team to resolve any issue they have. 

Check the System Requirements 

If your editor widget panel does not load this could also mean that your server has not met the minimum requirements demanded by Elementor. You need to make sure that all components on your system meet the minimum requirements. Check for these minimum requirements:

  • WordPress: Version 5.0 or higher
  • PHP: Version 7 or higher
  • Database: MySQL 5.6 or higher / MariaDB 10.0 or higher
  • Memory Limit: 128 MB or greater

You can check the server requirements from the WordPress Dashboard if you click on Elementor > System Info and see what is at a lower value than recommended. 

Check the theme 

Although rarely with any of our Neuron themes, sometimes an incompatibility issue between your current theme and Elementor can occur which then results in the widget panel not loading. To make sure your theme is not the culprit, change the active theme to a default WordPress theme like Twenty-Twenty. Go back to the Elementor editor and see if the widgets panel is loading properly. If yes, then please contact our support system as we will most definitely find a solution to your problem. If the widget's panel is still not loading, this means the theme is not at fault, and you can continue with the other solutions. 

Increase Apache Service Limit

Sometimes the server reaches its resource limits, in such cases, you can increase this limit by adding a code snippet to your .htaccess file. To do that simply:

  1. Log in to your FTP Client account or to your cPanel account. 
  2. If you are on cPanel, from the File Manager, locate the public_html folder
  3. There should be the .htaccess file, click on it

  4. Copy the following code and add it to your .htaccess file 

    <ifmodule mod_substitute.c="">
    SubstituteMaxLineLength 30m
    LimitRequestBody 9999999
  5. Save the .htaccess file for the changes to take place and see if the issue is resolved

Change Editor Loading Method

Elementor integrates an option to switch the loading method for the page builder. Although not much information is shared on the way this loader works, they suggest you enable the loader method if you are experiencing problems with the editor. To do that go to your WordPress dashboard and navigate to Elementor > Settings > Advanced. 

Here from the Advanced Tab, you should see the Switch Editor Loader Method, which by default is set to Disable. From the dropdown menu select the Enable option and click on Save Changes. Check fi the editor loads successfully after you've switched this method to Enable. 

Disable Unused Widgets

If you are using Elementor Addons, this could also be a culprit when it comes to displaying the "Elementor Widget Panel Not Loading" error. Make sure you disable unused widgets and check to see if the problem is still occurring, if not then you know these addons are at fault and you can either contact their support system or not use them. 

Other Common Causes

If the problem still persists even after you've ruled out all the solutions we provided above, it is probably best if you contact your hosting provider and have them give you the ModSecurity error logs. Check from the list of errors to see what's causing the problem and ask your hosting provider to help you resolve any problems with it. 

Another step you can take is once again to contact your hosting provider and have them make sure the PHP Zlib extension is enabled on your server. And lastly, there might be cases where you may need to increase the value of max_input_vars. Please contact your hosting provider to help with this task.
