Troubleshooting: Installation Issues

Things that can go wrong during installation and how to fix them. Check this before emailing me. I’m probably just going to tell you one of these things anyway.

Most installation issues come down to three things: hosting environment, plugin conflicts, or missing requirements. Here’s how to diagnose each.

Error: “The package could not be installed”

This usually means your hosting server can’t write to the wp-content/plugins/ directory. Check file permissions. The plugins folder should be 755 and files inside should be 644. If you’re on managed hosting, contact your host – they sometimes restrict plugin uploads for security reasons and need to be asked to allow it.

Plugin activates but admin menu doesn’t appear

This can happen if:

  • You’re logged in as a user who doesn’t have the manage_options capability. ManskiPort only shows to administrators.
  • There’s a caching plugin aggressively caching admin pages. Clear all caches and try again.
  • A plugin conflict is causing a PHP error on activation. Check your PHP error log.

White screen on activation

Usually a PHP memory or timeout error. ManskiPort requires at least 128MB PHP memory. Check your wp-config.php for WP_MEMORY_LIMIT and increase it if needed. Add this line if it’s not there:

define('WP_MEMORY_LIMIT', '256M');

Setup wizard doesn’t load

Make sure you’re running WordPress 6.0+ and PHP 7.4+. If you’re below those, the plugin won’t run correctly. Your hosting control panel will show your PHP version. If you need to upgrade PHP, ask your host – it’s usually a one-click operation in cPanel.

License key says “Invalid”

See the License Troubleshooting doc. The most common cause is a typo in the key or a server that can’t reach the license endpoint.

None of these fixed it

Email me at elijah@eplemanski.com with:

  • Your WordPress version
  • Your PHP version
  • Your hosting provider
  • The exact error message you’re seeing
  • A list of other active plugins if you have any

I respond within one business day. Usually faster.
