 * Hi there,
 * I understand that you’re experiencing slowness and encountering a JavaScript 
   error when updating post/page on your website. The error “Uncaught TypeError:
   e.O is not a function” suggests a JavaScript-related issue. 
   Please follow these
   steps, and let me know if it solved your issue:– Ensure that you are using the
   latest version of the Elementor plugin. Outdated versions may have bugs or compatibility
   issues. If an update is available, consider updating Elementor to the latest 
   release.– Clear your browser cache or try accessing the website using an incognito/
   private browsing window to rule out any browser-related caching issues.– Identify
   if there are any JavaScript conflicts. Reactivate all plugins except Elementor
   and switch back to your original theme. Check if the issue persists. If not, 
   gradually reactivate each plugin and switch back to your theme one by one to 
   pinpoint the conflicting element.– Check your server’s resource usage (CPU, memory)
   during page updates. Insufficient server resources can lead to slow performance.
   You may want to consult with your hosting provider to ensure that your server
   meets the requirements for running Elementor smoothly.
