Old Library Path Not Removed

Hi @donpwinston,
Can you please provide more details on it ? I tried with Drupal version 9.5.11 with same version as you described i.e. 8.x-1.7
Placed the Superfish menu block in header, Turned off css and js aggregation, Flushed Drupal and browser cache. Checked the page source, browser console as well as Drupal logs. I was unable to replicate the same.

I don't know what else to say. Do you have any idea how the <script src="/libraries/superfish/superfish.js?s2rxd0"></script> tag is showing up in my pages?

I've had headaches with caching. I've flushed Drupal caches, opcache, and APCu cache. Are there any others? At one time I downloaded the superfish library and copied it to /libraries/superfish but now I believe composer takes care of that and calls it drupal-superfish.

The library_path functions in superfish.module are a little confusing. Could I patch it to force it to use only /libraries/drupal-superfish without breaking anything? If so then how? Then I could be sure it is not the module code that is doing it.

I found the problem. I made a Drupal sub theme of bootstrap barrio and put a weight on the old superfish library. I need to change the name to drupal-superfish.

Sorry.
