Install and activate Plattio Forms – Documentation

What you will achieve: You will confirm your server meets the plugin requirements, install and activate Plattio Forms, and activate your license so premium modules are available in the plugin Modules page.

Prerequisites

Before you install, confirm these minimum system requirements:

WordPress version: 6.7 or later.
PHP version: 8.1 or later.
A WordPress administrator account.

Install the plugin

Log in to your WordPress admin dashboard.
Go to Plugins > Add New to install from the WordPress.org repository, or use Plugins > Add New > Upload Plugin to upload the plugin ZIP file from your computer.
After the plugin is uploaded or found, click Install Now, then click Activate.

After activation you should see a top-level admin menu called Plattio Forms (dashicon: feedback). Under that menu the plugin provides these pages:

Forms — list of forms.
Add New / Builder — open the form builder.
Entries — view submitted entries.
Templates — choose a form template.
Modules — enable or disable optional modules.
Settings — global plugin settings and license area.
Tools — import/export and system utilities.

Activate your license (required for premium modules)

Open Plattio Forms > Settings.
Ensure you are on the General tab (the Settings UI includes tabs such as General, Email, CAPTCHA — General contains the license controls).
Find the License key input (the saved key is shown masked when valid) and enter your license key in that field.
Click the Activate license button.

When activation succeeds the UI shows the license as valid and premium modules can be enabled in Plattio Forms > Modules. A masked key is shown when the license is active.

What to expect after completing these steps

The Plattio Forms menu and its subpages will be present in your admin menu.
You can create forms in the Builder and embed them using the plugin shortcodes (the Forms list shows the shortcode like [plattio_form id="<id>"]).
After license activation you can enable premium modules from Plattio Forms > Modules; the Modules page will indicate which modules require an active license.

Common activation issues and how to check them

Plugin won’t activate — confirm your server meets the minimum requirements: WordPress >= 6.7 and PHP >= 8.1. If requirements are not met, upgrade WordPress or PHP first.
License activation fails — check your internet connection and that outgoing HTTP(s) requests are allowed from your server. Ensure the license key is entered exactly.
- If activation returns an error in the UI, try again and note the error text. Common server-side causes include temporary network errors or the license server being unreachable.
Premium modules still say “Activate your license” — open Plattio Forms > Settings to confirm the license shows as active (masked key). If it is active but modules remain locked, reload the Modules page and check for notices; re-saving Settings may help.
Permissions — make sure you are using an administrator account; module activation and license controls require manage_plattio_forms capability (normally available to admins).
Secret/encryption errors — some settings (SMTP password, API keys) are saved encrypted; if the UI shows a secret save error (for example mail_secret_error) follow the on-screen guidance and re-enter the secret after confirming server support for PHP crypto functions.

If you still have problems

Confirm WordPress and PHP meet the minimum versions.
Temporarily disable other plugins that manage mail or licensing if they conflict (conflicting SMTP plugins can interfere with mail testing).
Check admin notices on the Modules and Settings pages for pf_notice messages (e.g. license_required, module_error) after attempting activation.
Contact your hosting provider to confirm outgoing HTTP requests are allowed and that required PHP functions are enabled.

If you complete these steps and need further help, include the exact error messages shown in the Settings or Modules pages when contacting support.
