Watcher Field not working on one server but working on another

[Eric Gasior]

I have two JIRA installations, both with JIRA Watcher Field installed. The one running 6.3.15 works properly. The one on 6.4.1 does not.

It does not appear under the Custom Field admin page so I can't assign it to screens.

Thank you in advance,

And with all modules enabled, not just the addon.

Have you tried adding a new watcher field in the Custom Fields page? Does it list the watcher field type at all?

[Eric Gasior]

It does not list the new watcher field in the Custom Fields page, even after uninstalling and reinstalling the plugin.

What version of the addon do you have in the JIRA instances?

[Eric Gasior]

I have version 2.6.0.

Can you double check if the add-on is enabled?

And the right version for 6.4

[Eric Gasior]

The add-on and all modules are enabled. The version of JIRA Watcher Field is 2.6.0, which the Marketplace lists as compatible with JIRA 6.4.
