LT Thermix FAQ
Which WordPress version do I need?
WordPress 6.6 or newer (tested up to 7.1) and PHP 7.4 or newer. It is a block theme, so you edit everything in Appearance → Editor.
What is the difference between Free, Pro Standard and Pro Unlimited?
Free is the theme package: templates, header and footer, fonts and all 4 colour styles, with a small credit link in the footer. Build your own pages, or install it on an existing website and keep your content. Pro Standard adds the ready-made homepage, 15 section patterns and the Services, About and Contact layouts, ticket support and credit removal. Pro Unlimited adds the AI kit, unlimited websites and lifetime updates and support.
Can I install it on my existing website?
Yes. If your site already has a static homepage (Settings → Reading), LT Thermix keeps it and shows your page with the new design. Your pages and posts stay as they are.
Can I use it without AI?
Yes. It is a normal WordPress block theme. The AI kit only makes setup faster if you use Claude, ChatGPT, Cursor or Copilot.
How do I add online booking or a service request form?
Point the Schedule service and Join this plan buttons to your booking system, or add your form or booking plugin’s block to the Contact page.
Are the demo prices, plans, brands, reviews and 24/7 claims included?
They are placeholders that show the layout. Replace them with your own plan prices and terms, the brands you really service, real reviews, your emergency hours and your licence, guarantee and financing details; in Pro Unlimited the theme checker lists anything you missed.
How do I get the Pro version after buying?
Right after payment you receive a licence key by email. Enter it on block.ltheme.com/account to download your theme and every update included in your plan.
How do I get support?
Pro Standard and Pro Unlimited include ticket support at ltheme.com/ticket-support. Free users can follow the documentation.
