Drop-in appeared causing problem with functionality

Hello,

I tried to install the hello bar but ended up deleting it. Now a drop-in has appeared which is affecting functionality.

It says install.php custom install script.

This little blurb “Drop-ins are advanced plugins in the wp-content directory that replace WordPress functionality when present” doesn’t help me because I don’t know which file it is in wp-content.

I don’t feel comfortable deleting any files from wp-content.

Please advise.

Thank you!
