@qasumitbagthariya I'm seeing failures on trunk when bumping to WP 6.4. Are you certain your tests passed?

@jeffpaul
It works for 2.6.0 but does not work with the trunk branch.

I re-ran the tests and they passed this time.

Approving, not tested the plugin thoroughly.

@qasumitbagthariya can you please test again and then it'll be good to merge?

The functionality works when downloading the plugin from https://wordpress.org/plugins/simple-page-ordering/ but looks like an issue when we download from the git release zip and trunk branch.

Can you please check from your end?

The issue is not a blocker for this PR so I'm approving this PR. ✅

@qasumitbagthariya since the issue doesn't seem to be related to WordPress 6.4, could you please open a separate issue ticket for it? Once that's done, we can merge this PR.
