Hi there @noahsbarks ,

I’m sorry to hear the issue persists. This is very odd because I confirmed that posts in the Movie and Music category use the same post template, so the form should appear on all posts.

I’m starting to suspect this is a conflict with another plugin on your website. Could you please perform a conflict test on a staging site to confirm if another plugin is affecting the MailPoet forms display?

You can find detailed instructions here: How to Test for Theme and Plugin Conflicts

Let us know your findings!

thank you, @salutethepig ! I see that our team is already in touch with you via email, so I’m closing this support thread. Thank you!

Hi there,

I’m sorry to hear the issue persists.

As you’ve been facing this issue for several days, to speed up the troubleshooting process, please contact us via https://www.mailpoet.com/support/sales-pre-sales-questions/ and include a link to this thread.

Also include a copy of your System Info in MailPoet > Help.

Thank you!

Hi @getsnoopy,

Thanks so much for the detailed info — that’s really helpful!

Looking at your system info, I noticed you have All In One WP Security & Firewall active. Security plugins like this can sometimes interfere with how reCAPTCHA scripts load and communicate with the form, even when there are no visible errors in the console. This could explain why the reCAPTCHA token isn’t being included with the form submission in checkbox mode, and why invisible mode silently fails to fire the request.

Could you try the following steps?

Step 1: Rule out a plugin conflict

Temporarily deactivate All In One WP Security & Firewall, Getwid, and Twentig — then test your shortcode form again with both reCAPTCHA modes. If the form works after that, re-enable them one at a time to identify the culprit.

Step 2: Run a quick diagnostic

If the issue persists even with those plugins deactivated, open the page with the shortcode form, press F12 to open the Developer Console, and paste this into the Console tab before submitting the form:

document.querySelectorAll('.mailpoet_recaptcha_field').forEach(f => console.log('widgetId:', f.value));

Let us know what value is logged. This will tell us whether the reCAPTCHA widget is being properly initialized on the shortcode-rendered form.

Step 3: Try the MailPoet Form block as an alternative

While we investigate, you can work around this by using the MailPoet Form block directly in the block editor instead of the shortcode. In the page editor, click the + button to add a block, search for “MailPoet,” and select your form. This uses a different rendering path and should work with reCAPTCHA enabled.

Looking forward to hearing how it goes!

Hi there,

Thanks for updating the thread with the solution you found. If the issue returns, I’d recommend following these troubleshooting steps:

Step 1: Rule out your browser

Open your site’s wp-admin in an incognito/private browser window (with all extensions disabled) and try editing the form again. Ad-blockers and security extensions are the most common cause of blank MailPoet admin pages — they can block the scripts MailPoet needs to load the editor.

If the form editor loads fine in incognito, the issue is a browser extension. You can then disable your extensions one by one in your regular browser to identify which one is causing the problem.

Step 2: Rule out plugin/theme conflicts

If the issue persists in incognito, the next step is to test for a plugin or theme conflict:

1. Go to Tools → Site Health → Troubleshooting in your WordPress dashboard and click “Enable Troubleshooting Mode.”
2. This will temporarily disable all other plugins and switch to a default theme — only for you, not your visitors.
3. Activate only MailPoet and try editing your form.
4. If it works, re-enable your theme first, then your other plugins one at a time, testing after each, to find the conflict.

Here’s MailPoet’s full guide on conflict testing: How to Test for Theme and Plugin Conflicts

Step 3: Clear your caches

Since your welcome popup is also showing blank on the front end for visitors, please make sure to clear all caches — your caching plugin, any CDN cache, and your server/hosting cache. Sometimes an older cached version of the page persists after a plugin update.

Also, please make sure you’re running the latest version of MailPoet (currently 5.23.0). You can check this under Plugins in your dashboard.

I hope this helps!

Hi there,

Thanks for reaching out!

We’ll be able to provide you with more information there.

Cheers!

Hi @vasilisweb,

Thanks for trying that and for sharing the updated logs. Since the deactivate/reactivate didn’t resolve the database errors, let’s try a fresh reinstall of the free plugin via FTP. This can help when the migration process gets stuck, especially after a large version jump like yours (3.87.x → 5.22.x).

Don’t worry — this won’t affect your data. All your subscribers, lists, newsletters, and settings are stored in the database, not in the plugin files, so they’ll remain intact.

Step 1: Reinstall the free plugin via FTP

1. Connect to your site via FTP (or your hosting file manager).
2. Navigate to /wp-content/plugins/.
3. Delete the mailpoet folder entirely.
4. Download the latest version of MailPoet from here: https://ww.wp.xz.cn/plugins/mailpoet/
5. Upload the freshly downloaded mailpoet folder to /wp-content/plugins/.
6. Go to your WordPress dashboard → Plugins and activate MailPoet.

After activating, check whether the database errors are gone. You can verify by visiting MailPoet → Help → System Status.

Step 2: Update the Premium plugin

Once the free plugin is working without errors:

1. Log in to your MailPoet account at https://account.mailpoet.com/.
2. Download the latest Premium plugin zip file from there.
3. In your WordPress dashboard, go to Plugins → Add New → Upload Plugin.
4. Upload the zip file you just downloaded and activate it.

If you’re unable to access your MailPoet account because it’s linked to the previous developer, you can also try entering your license key in MailPoet → Settings → Key Activation — the Premium plugin should be installable from there as well.

Please let us know how it goes!

Hi there @salutethepig,

Thanks for getting back to us with more details.

Note that Post Notification emails typically display posts that haven’t been sent in previous Post Notification emails. Looking at the screenshots you’ve sent, it seems that the following happened:

• A Post Notification email was sent on March 9th.
• The following Post Notification email was sent on March 11th, including the posts that were published after March 9th (the ones published on March 10th and March 11th), as they haven’t been included in March 9th’s Post Notification.

If you only want to include one post in each Post Notification email, even if there are multiple newly published posts, you will want to make sure that the Automatically Latest Content widget is set to display only 1 post.

Does that make sense?
