Unable to fix query error message.

I am also having this problem.

WP Sticky Notes v2.1.5
WordPress v4.4.1
Hosted on Linux VM running Apache2 and MySQL 5.6

Has anyone found what this issue is with this?

You might try targeting a user by starting your sticky note off with an @ followed by the user you want to target.

I think that the problem is that, without explicitly adding users to a note, the “target users” list that is sent to the query is null (empty list).

In the install portion of plugin.php, this line is included in the db table create code:
target_users varchar(200) NOT NULL

So, the db table requires non-null values for target_users, but the code uses an empty list to indicate that there are no users explicitly associated with a note.

Anyone know how to fix this? I’m a php WordPress newbie.

I am still trying to get this plugin to work and receive the jquery error message also! “Something wrong with query”. As above the fix works when typing in the admin email with the @symbol. So @admin or whatever your username is. Is there a fix for this without having to do this as I think this plugin is absolutely brilliant it is so handy for me to outline content throughout the design. I know the older versions worked spot on! Would love to know how to resolve this.
