Hi Jerome! Thank you for your reply hank you very much for your answer, I have installed the 3.0 version of oembed in my mod folder, however the plugin comes up with a manifest file message. I have tried to move the folder, but I keep getting the same message. I don't know how to solve this problem. The message I get is: Missing manifest file in the package is not a valid plugin. Location:/Home/qclsqhcf/public_htm/mod/oembed/

If you're getting a message 'Missing manifest file' then your not using Elgg version 4.x.

Please make sure you use the correct compatible version of Oembed for your Elgg installation. https://elgg.org/plugins/2932901.

To check your Elgg version:

• for Elgg 3.1+ you can see the version in the page title when visiting /admin
• for Elgg > 3.1 go to /admin/server

Hi Jerome Thank you again! I remeber that i have installed Elgg in my domain via softaculous and I had version 3.3.
