Payo Speed Pro

1. Overview

Payo Speed Suite Pro is designed to improve Joomla performance without aggressive CSS/JS merging that can break layouts, carts, menus, or page builders.

2. Requirements

3. Installation

1. Log in to the Joomla Administrator area.
2. Go to System → Install → Extensions.
3. Upload pkg_payospeed_1.3.6.zip.
4. After installation, go to Components → Payo Speed Suite Pro.
5. Open Plugin Settings and enable System - Payo Speed Suite Pro.

4. Quick Start Recommended Setup

Use these settings first on every Joomla website:

Mode: Safe
Smart Guest Page Cache: ON
HTML Minify: ON

Skip First Images: 1
Preload LCP Candidate: ON

5. Admin Dashboard

The component dashboard is available from Components → Payo Speed Suite Pro. It includes:

• Dashboard: plugin status, cache files, cache size and current mode.
• System Check: Joomla/PHP compatibility, writable cache, GD/Imagick/cURL and plugin status.
• Images: scans large images and can generate WebP copies.
• Extensions: detects common Joomla builders, shops, templates and form extensions.
• Logs: records cache hits, stores, exclusions, WebP generation and optimization actions.
• Docs: quick safety reminders inside Joomla admin.

6. Plugin Settings Explained

Mode

Safe is recommended for the first run. Balanced and Advanced settings should be enabled gradually after frontend testing.

Smart Guest Page Cache

Stores optimized HTML for public guest visitors. Logged-in users and excluded pages are not cached.

HTML Minify

Removes unnecessary whitespace from HTML output. This is safe for most websites.

Lazy Load Images

Adds lazy loading to images below the first screen. The first images can be skipped to protect LCP.

Preload LCP Candidate

Attempts to detect the first important image/background and preload it for faster Largest Contentful Paint.

Serve WebP Images

If .webp copies exist next to JPG/PNG files, the plugin can serve them through safe <picture> fallback markup.

Safe JavaScript Defer

Defers safe scripts while protecting critical Joomla, menu, form, cart and checkout scripts.

Async Non-critical CSS

Optional. Keep it OFF until the site is tested. Some templates/builders depend on blocking CSS order.

Delay Third-party Scripts

Optional. Can delay Analytics, Pixels, Hotjar, TikTok, Clarity or similar third-party scripts. Test tracking and consent tools after enabling.

7. Image and WebP Workflow

1. Go to Components → Payo Speed Suite Pro → Images.
2. Review large files from /images and /media.
3. Click Generate WebP for Large Images.
4. The tool creates .webp copies next to original JPG/PNG files.
5. Original images are not overwritten, cropped or resized.
6. Enable Serve WebP Images in the plugin.
7. Clear cache and inspect the frontend source.

<picture>
  <source type="image/webp" srcset="/images/example.webp">
  <img src="/images/example.jpg" alt="">
</picture>

8. Cache Tools

Clear Cache

Deletes generated Payo Speed page cache files. Use it after changing layout, menus, modules, template options or plugin settings.

Warm Up Cache

Requests the homepage and public menu links to create guest cache before real visitors arrive.

Automatic Exclusions

Payo Speed excludes dynamic areas such as cart, checkout, login, profile, administrator, token-based requests and common shop/form actions.

9. Safe Testing Checklist

After installing or changing settings, test:

• Homepage
• Article page
• Category/blog page
• SP Page Builder/YOOtheme/Quix pages if used
• HikaShop/VirtueMart product category
• Product detail page
• Add to cart
• Cart page
• Checkout page
• Login/register/profile pages
• Contact and other forms
• Mobile menu

10. Troubleshooting

The layout looks broken

1. Disable Async Non-critical CSS.
2. Disable Delay Third-party Scripts.
3. Clear Payo Speed cache and Joomla cache.
4. Test again in incognito.

Cart or checkout behaves incorrectly

1. Make sure shop/cart/checkout URLs are excluded.
2. Disable page cache temporarily.
3. Clear cache and test again.

WebP files are not created

1. Check GD/Imagick in System Check.
2. Verify /images and /media permissions.
3. Increase PHP memory limit for very large images.

Admin dashboard style does not update
