 * Urgent cannot edit Mail Poet forms – blank screen. I have a welcome popup that
   is now showing up blank after the update and I cannot edit the forms a blank 
   screen results. Have done conflict testing and switched off caching but to no
   avail. Any pointers would be appreciated. Thanks

 * 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](https://kb.mailpoet.com/article/204-how-to-test-for-plugins-conflict)
 * **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!
