Notice: Undefined index: plugin

@salmanjaveed I’m sorry, but I’m unable to replicate the issue you are having. Can you provide some more details? What version of WordPress are you running? Are you using the block editor or classic editor? Have you tried checking for plugin conflicts? (I recommend Plugin Detective).

@wpscholar thank you for replying.

We are on WP 5.7.1 PHP 7.4.15 Classic editor (with plugin) but Elementor to edit pages.

It was working well and suddenly started with the warnings apparently for no reason at all. I have the same setup running on a dev site but that is working well. And, it’s impossible to deactivate plugins and check on the live site.

@salmanjaveed I’ve tested with the same WordPress version, PHP version, both the block editor and classic editor, with Elementor active… still not able to replicate the issue. Without a way to further help you debug, I’ll have to leave it up to you. It sounds like maybe it is a plugin conflict, but if you’re running the same plugins on a dev site, it may be an environmental difference. If you’re able to narrow it down, I’d be happy to try and replicate the issue again and see what I might be able to do to fix it.

@wpscholar can you tell me if uninstalling and re-installing the plugin remove the ‘marker’ data from the database.

I think that removing the plugin and installing it again may clear the issue, I have tried various options with the dev site and I am unable to replicate that issue myself too. But, I did check that removing the plugin left the data in the postmeta table untouched. Can you confirm this, please?

@salmanjaveed Yes, you can safely delete and reinstall the plugin without losing the data in post meta.

@salmanjaveed Version 1.1.3 should fix this issue for you. Turns out the issue only happened when the Yoast SEO plugin was active, but the issue was in my code.

Micah @wpscholar – thanks it did fix my problem (I am now working on this, taking over Salman’s role), it works beautifully!

Awesome! Thanks for letting me know!
