i use audacity 2.3.0 win7

In the “Regular Interval Labels” effect, click on the “Manage” button and select “About”. What version does it say?

Version: 2.3.0

I have teamviewer, you can control my PC , for view the error, if you want reproduce the error.

I test the Audacity 2.3.1-alpha-Oct 22 2018, and the Regular Interval Labels now work.

The alternative solution was that you could have used the older Audacity 2.2.2 version of the plug-in.
The problem was this bug, and is specific to Audacity 2.3.0:

There’s been quite a few bug fixes since October, so it may be better to go back to 2.3.0 until the “Release Candidates” become available (they will be announced here on the forum, and on facebook / twitter / G+). Release candidates are scheduled to appear shortly before Christmas.

To use the 2.3.1 version of “Regular Interval Labels”, simply make a copy of the file “equalabel.ny” from the plug-ins directory, install Audacity 2.3.0, and then overwrite its version of “equalabel.ny” with the 2.3.1 version.

ok steve very thanks. I will do what you have suggested to me.

I almost forgot (ok, so I did forget); “Regular Interval Labels” in 2.3.1 has been updated.

“Regular Interval Labels” 2.3.0 and earlier:

“Regular Interval Labels” 2.3.1 (alpha):

I use the pluguin 2.3.1 in 2.3.0 and work fine.
