From a single-page WordPress site
to an online store WooCommerce, Laravel, NextJS

The website was redesigned (view the previous page) while improving search engine optimization and performance. It provides information about cars and motorcycles, including specifications and guides to operation, maintenance and repair. Custom features include a document viewer, forms and theme switches. The original neumorphic design offers light and dark themes and is optimized for Core Web Vitals. Desktop PageSpeed scores reached 100 (new page and previous page).

A website offering construction and renovation services in Frankfurt. Given the local legal requirements and approach to website promotion in the German market, with less emphasis on links and more on natural visitor behavior, we built a simple website optimized for Google and Core Web Vitals. The achieved scores are 100 or close to it, even though Redis caching in the NGINX web server is used only for dynamically generated emails submitted through the website form.

The website was migrated from REG.RU hosting to mchost.ru. The migration also resolved database and character-encoding issues affecting custom functionality in the administration panel.

WLN Multi-Provider AI Chat is a fully configurable chatbot for WordPress websites. Site administrators choose an AI endpoint and model, supply credentials, and configure the widget. Replies are generated by the configured service.

• OpenAI, Anthropic Claude, Google Gemini, YandexGPT, OpenRouter, local Ollama, and custom OpenAI-compatible endpoints.
• Model selection, generation parameters, and system instructions.
• A local knowledge index of published, publicly viewable posts and pages without passwords, plus administrator-supplied Markdown documents.
• Current page context and limited conversation history.
• Configurable colors, fonts, dimensions, widget position, and welcome message.
• Signed visitor sessions, rate limits, and encrypted storage of saved API keys.
• Conversation statistics, retention settings, and visitor-controlled history deletion.
• Bundled Russian translation and Polylang integration for saved widget strings.

Plugin features require no paid plugin license or subscription. External AI providers may charge for requests.

• WordPress 5.0 or newer.
• PHP 7.4 or newer.
• PHP OpenSSL with AES-256-GCM support for storing API keys.
• Network access from the WordPress server to the selected API or local Ollama server.

1. Open Releases and download the plugin ZIP from Assets. For version 1.4.8, use wln-multi-provider-ai-chat-1.4.8-wordpress-org.zip.
2. In WordPress, open Plugins → Add New → Upload Plugin, select the ZIP, install it, and activate the plugin.
3. Open AI Chat → API Settings: enter the provider, API endpoint, model, and key. If local Ollama does not require authentication, enter a non-empty placeholder such as ollama.
4. Test the connection and save the settings.
5. Configure the appearance in Widget Settings. Optionally add Markdown documents to the knowledge base.

The floating widget appears on the website. Supported shortcodes include 

When migrating from GSXR-777 AI Open Chat, back up the site, deactivate the old copy, install and activate the new copy, and verify its settings. Changing the directory and main PHP filename requires manual activation.

Do not activate both copies together. If the old plugin is configured to remove data on uninstall, do not use the WordPress Delete action: both copies share stored data. Settings, keys, tables, and legacy shortcodes are retained for compatibility; deactivation does not delete settings.

Conversations and statistics are stored in the WordPress database. Signed session credentials are stored in the browser localStorage so visitors can continue a conversation after reloading the page.

AI requests are sent when a visitor submits a message or an administrator tests the connection. The selected service receives the API key, model, generation parameters, system instructions, message, limited history, and relevant knowledge excerpts. When page context is enabled, requests may also include its URL, title, content excerpt, and text selected by the visitor.

Only add knowledge intended for public visitors. On sites with third-party access restrictions, review the index content. Update the privacy notice to describe conversation storage and the selected service. Full service disclosures and policy links are available in readme.txt.
