Plugin Installation Issue

Hi all, 

I need some help with plugin installation on a web hosting.

I have installed a plugin Event Manager onto my web hosting (123reg). When activating the plugin though, the website fails any I get the HTTP ERROR 500.

Once removing the files, and the Elgg is up and running again, I see this message 

event_manager-master (guid: 39) cannot start and has been deactivated. Reason: Cannot include start.php for plugin event_manager-master (guid: 39) 

Is anyone able to shed a light on this?

  • Seems, you've downloaded Event manager from GitHub source page but not from releases. It's wrong.

    So the right way is:

    /mod/event_manager not /mod/event_manager-master

    Also, be sure that your Elgg version is compatible with this plugin.

    Now, how to fix your issue:

    1. If you see the Notice message on Administration only then dismiss it by clicking on x.

    2. You can activate Elgg Developers Tools plugin (available on your Plugins by default) and under Develop -> Tools menu section click on Entity Explorer tool.

    Enter your failed plugin guid: 39 -> Submit -> Remove this entity.


    Now you can install Event Manager again.

    Use the latest version for Elgg 2.3.x only. Version for Elgg 3.x under development yet.
