Follow that documentation to create Child Theme  Child Themes – Codex

Using that plugin to create Child Theme: Child Theme Generator

You need to use a Child Theme only if you are making code customizations.

At the time of installation you may get a message like “Import failed,” . in that case it means your server PHP configuration limits is the reason for the problem. You should contact your hosting provider and asked them to increase those limits to a minimum as follows.

max_execution_time 300 or above
memory_limit 128M
post_max_size 32M
upload_max_filesize 32M

You can verify your PHP configuration limits by installing a simple plugin. You will find it here https://wordpress.org/plugins/php-info-wp/

You can also check your PHP error logs to see the exact error.

If you get a 502 error when you try to edit with Elementor you have to do two things:

Go to  Elementor > Settings > Advanced, and under ‘Editor Loader’, enable ‘Switch front-end editor loader method’.

This setting changes the Elementor editor loader method.
You then may need to increase a particular Apache service limit. To do that, add the following lines inside the website’s .htaccess file:

				
					<IfModule mod_substitute.c> SubstituteMaxLineLength 10M </IfModule>
				
			

You can edit that file via SSH, FTP, or the File Manager tool in cPanel.

While importing the demo data your server configuration may not be enough for the demo data importation.

In that case, you may have to perform a manual demo import.

Below are the steps for the manual demo import.

Step 1: Go to tools >> import >> WordPress import

If the WordPress importer is not installed or activated then install the WordPress importer

here import the content.xml

You will find the file in the WordPress installation folders wp-content >> plugins >> [theme name]-demo-installer >> demo data >> demo

Step 2: install the widget importer & exporter plugin.

 

then go to tools >> widget importer & exporter

there upload the .wie file if uploading doesn’t work then copy its content and use copy-paste method.

Step 3: Install customizer export/import

then go to appearance >> customize >> export/import

there use/import the .dat file

Step 4: And lastly, import the base theme options

here upload the json file or you can copy paste the content here too
The demo import files are found in your WordPress installation folder’s wp-content >> plugins >> [Theme name]-demo-importer >> demo data

Sometimes while changing the settings you may face errors on saving the changes, Normally a user may face this type of errors saying “Invalid security credential. Please reload the page and try again.

If you face this error please check if your Redux Framework plugin is activated in Demo mode or not. If it’s activated then please deactivate it which will solve the issue.

This error is usually caused by a lack of memory (to be sure, ask your hosting company to send you the PHP error logs of your server). When you experience this issue, one of these solutions might help:

Erase some sections in the page that you are trying to save and see if it enables you to perform the action (you can retrieve them by using the revision history of Elementor).

Increase the WP memory limit. You can fit the memory limit to our requirements and activate the debug mode of WordPress to check how many MB you need exactly. Although you can do it by yourself, it is preferable to contact your hosting provider for further assistance.

If the issue still occurs after increasing the memory, divide your work into a few templates and paste them into another page.

Sometimes, saving issues can happen when the admin-ajax.php script timeouts. You can know if it is the issue by checking the error messages appearing in your browser console. The error message, in this case, is Failed to load resource: the server responded with a status of 413. When you experience this problem, add the following directives to your .htaccess file to increase the dynamic timeout:

				
					<IfModule mod_dtimeout.c> <Files ~ ".php"> SetEnvIf Request_URI "admin-ajax.php" DynamicTimeout=150 </Files> </IfModule>
				
			

This can also be due to parameters set on your server. For instance, HTTP/HTTPS conflicts. Adding an SSL certification to your site can solve the issue. Then you will have to change the URL of the site from your WP Dashboard in Elementor > Tools > Replace URL.

403 error when attempting to update a page: This can be due to a security plugin such as WordFence and others. To sort this out, activate the learning mode of this plugin or contact their support. This issue can also be due to the firewall of your server so this has to be checked with your hosting company.

If the aforementioned troubleshooting procedure doesn’t help you, please send us your system info so we can try to help you solve the problem.
