 * Hi,
 * This is a conversation between WP developer and me.
    and the developer said there
   is a coding error in H5P plugin.
 * Me: Hello,
    I cannot open “WP Admin” Page. What should I do?
 * WP: Hi there! Do you get any errors when you try and open it?
 * Me: Yes, it shows “500 Internal Server Error”
 * WP: Okay, that’s usually a plugin conflict. Did you install a plugin recently?
   Looks like it’s the h5p plugin. Does that sound familiar?
 * Me: Yes,
 * WP: We’ll need to deactivate this plugin. Are you able to do it from your end?
 * Me: I use H5P Plugin. So should I inactive it??
 * WP: Yes, it’s causing the error.
 * Me: Okay, thank you!
 * WP: Can you deactivate it on your end?
 * ME: I cannot inactive it
 * WP: okay, let me do it for you.
 * Me: it shows”No plugins are active.”
 * WP: okay, I have deactivated it for you, the site should be back up now. I would
   recommend not using this plugin again in the future. You can look for an alternative
   instead.
 * Me: Hmmm, but it is the most important plugin for my site
 * WP: What is it for?
 * Me: making interactive quiz and so on
 * WP: I see. It is giving us some coding errors though. Maybe you can try asking
   the plugin developer to take a look.
 * Me: If I active it, do you think the same situation will be happen?
 * WP: Yes, it will happen again unless the plugin is fixed. This is the error:
   
   PHP Warning: require_once(/opt/sites/1031858/wpcom-127523526/wp-content/plugins/
   h5p/autoloader.php): failed to open stream: No such file or directory in /opt/
   sites/1031858/wpcom-127523526/wp-content/plugins/h5p/h5p.php on line 33
 * Me: Okay, I will let the developer about the error! Thank you
 * WP: Sounds good. Otherwise, maybe you’ll need to think about using a different
   plugin but hopefully they can fix this for you.

 * It looks like you are missing files from the plugin folder or the web server 
   does not have permission to read them.
 * Check if you can find the file wp-content/plugins/h5p/autoloader.php. If it’s
   not there something went wrong while downloading and unzipping the plugin. You
   can fix the issue by manually downloading the zip file, unpacking it and replacing
   your current h5p plugin folder with it.
 * If the file does exist it’s probably a permission problem.
