 * I am using the latest version of this plugin and when there is no content, the
   plugin works flawlessly in the backend, but as soon as I ad 5 units with 15 modules
   each, the backend becomes super laggy and each ajax requests this plugin sends
   takes up to 15 seconds, what could be the problem?

 * Hello [@katsar0v](https://wordpress.org/support/users/katsar0v/)
 * Hope you’re doing well!
 * Please deactivate all other plugins and revert temporarily to a default WordPress
   theme. This will help us rule out any potential conflicts, let me know if the
   loading speed is improved.
 * What is your site memory limit? Please increase it to 256MB by adding the following
   line to the wp-config.php file:
    `define( 'WP_MEMORY_LIMIT', '256M' );`
 * If it is set to 256, please try to increase it to 512MB.
 * Let me know how it went!
 * Cheers,

 * Hi Nastia,
 * I have tried disabling all plugins and returning to the default theme, as well
   putting the memory limit 512MB. What I noticed though is that, if I have a unit
   and add 5 modules, it is the front-end that is blocking (poor javascript). The
   php and nginx server are completely free (0% load), but the browser is on 100%.
   Just try having a demo course with 5 units, each with 15 modules and then add
   a module in any unit, you will notice how the browser seem to block.
 * Greetings,
    Kristiyan

 * Hello [@katsar0v](https://wordpress.org/support/users/katsar0v/)
 * I’ve tried to replicate the same, but I couldn’t reproduce the browser’s 100%
   usage. Would you please export the course from CoursePress > Export and attach
   it here?
 * I could see a JS error though from my end `Uncaught TypeError: Cannot read property'
   id' of undefined`. I’ve reported this error to our developers.
 * Please advice,
 * Kind regards,
    Nastia
