panel wront open in elementroe code example

Example: elementor widget panel not loading

There are some steps that i performed to solve this issue:

1. Ensure you meet the system requirements. You can check if your system meets
these requirements by going to Elementor > System Info. Two of the main things
to check are the PHP version and memory limit, but also take note of any other
items that might indicate a problem.

2. Make sure you are using the most updated versions of Elementor, Elementor
Pro (if you are using that), WordPress and your theme. Sometimes it isn’t
obvious that there is an update available. Go to Dashboard > Updates and
click the Check Again button to be sure.

3. If the problem persists, ask your hosting company to provide you with 
ModSecurity error logs and resolve any problems from it. Also, ask your hosting
company to make sure the PHP Zlib extension is enabled on your server.

4. Always check you debug.log inside wp-content. It will tell you the exact 
issue that is causing this issue.

5. WordPress Memory Exhausted Error – Increase PHP Memory. You need to paste 
this code in wp-config.php file

define( 'WP_MEMORY_LIMIT', '256M' );
