Embed code not working

Hi great plg for Joomla. Can you delete all articles by user too?

What is displayed in this module? Are these users who are currently logged in, or is this a list of all users from which we can choose which user to log in as?

Is there any way to modify the language on the page? The text is "Press correct password to read post". This is confusing as there is nothing to press. It should read type or enter and there should be a clear box to fill in the password, which is not easily viewable or eminently clear at a glance. And unlock should say something like submit or click here. I'm guessing this is in the code, and not editable, but just checking, thank you!

I am confused on something and hoping you can clarify things. Please see this video for a visual example: https://screenrec.com/share/Xbw03sSjhc

I migrated about a thousand items with attachments from K2 using your tool and attachments plugin. I initially did this on a test account. Everything worked fine over there. The migrated article attachments worked fine. Then I backed it all up and moved it to my live domain. Now none of the attachments load. All I get is Exception File Not Found and I can't figure out where to look. Turning on error reporting and debug don't tell me anything. I am guessing the old files were not moved during the migration correct? Or how does that all work? I still have all the original folders in the original places as far as I can tell.

The component managed to convert the K2 items to articles, but when clicking on an article in the backend this error pops up:

An error has occurred. 0 implode(): Argument #2 ($array) must be of type ?array, string given

Return to Control Panel

Any idea what's causing this?
