FAQ

Do I need both Gemini and OpenAI API keys?

No, you only need one. Choose either Google Gemini API or OpenAI API based on your preference and budget.

How much does it cost to use this plugin?

The plugin itself is free, but you’ll need an API key from either Google Gemini or OpenAI. Google Gemini offers a free tier with 15 requests per minute. OpenAI charges per token usage (~$0.15 per 1M tokens with GPT-4o-mini).

Can I add languages not in the preset list?

Yes! Go to Settings Lifegence AITranslator General tab, scroll to the “Custom Languages” section. Enter the language code (e.g., tl for Tagalog) and name, click “Add Custom Language”, then save settings. Custom languages will appear in all language selectors.

Can I edit translations manually?

Yes! Simply click “✏️ Edit Translation” in the admin bar (or add ?edit_translation=1 to the URL), then click any text on the page to edit it. Type your correction, save, and refresh. Perfect for fixing brand names, technical terms, or adjusting tone.

How does caching work?

The plugin caches all translations using WordPress Transients. This means once a page is translated, subsequent visits load instantly from cache without making API calls. Cache duration is configurable in settings (default: 7 days).

What happens if I hit API rate limits?

The plugin optimizes API usage by translating entire pages in a single request and caching results. If you hit rate limits, you can:
* Enable caching to minimize API calls
* Wait a few minutes before retrying
* Upgrade to a paid API tier

Can I use this with other multilingual plugins?

This plugin is designed to work standalone. Using it with other translation plugins like WPML or Polylang may cause conflicts.

Is this plugin SEO-friendly?

Yes! The plugin generates proper hreflang tags, uses clean language-prefix URLs, and updates HTML lang attributes for proper search engine indexing.

How do I add a language switcher to my site?

Use one of these methods:
* Widget: Go to Appearance Widgets and add “LG Language Switcher”
* Shortcode: Add [lg_lang_switcher type="dropdown"] to any page or post
* PHP: Add <?php echo do_shortcode('[lg_lang_switcher]'); ?> to your theme

Can I force re-translation of all content?

Yes! In Settings Lifegence AITranslator Cache tab, click “Increment Cache Version (Force Re-translate)” to invalidate all existing translations and force fresh translation on next page load. This is useful when you want to refresh all translations after improving translation prompts or when translations need systematic updates.

What content gets translated?

The plugin translates:
* Page and post titles
* Page and post content
* Excerpts
* Widget titles and text
* Menu items
* Category and tag names
* Custom post types

What content does NOT get translated?

The plugin automatically skips:
* URLs
* Email addresses
* JavaScript code
* CSS styles
* Numbers and symbols only
* Very short text (< 2 characters)
