Customize WordPress with CT OEM Logo Changer: Tips & Tricks

How to Use CT OEM Logo Changer — Step‑by‑Step Tutorial

What it does

CT OEM Logo Changer replaces or customizes the default OEM/logo images used by a theme or plugin (commonly for WordPress-based admin areas and login screens), letting you upload your own branding without editing core files.

Before you start

• Backup: export your site files and database or create a restore point.
• Prepare assets: have logo files ready (PNG or SVG recommended), with sizes matching your theme’s requirements (e.g., 200×50 px for header, 300×300 for avatar).
• Access: administrator access to the WordPress dashboard or server files as needed.

Step-by-step setup (assumes WordPress plugin)

1. Install the plugin

   • In WP Admin go to Plugins → Add New → search for “CT OEM Logo Changer” → Install → Activate.

2. Open plugin settings

   • Go to Settings or Appearance → CT OEM Logo Changer (location varies by plugin).

3. Upload logos

   • Use the provided upload fields to add your primary logo and any secondary or favicon images. Acceptable formats: PNG, JPEG, SVG (if supported).
   • Replace default images: click Replace/Remove on each existing item and choose Media Library or Upload.

4. Set placement and sizing

   • Configure where each logo appears (header, login screen, admin bar) and set width/height or let it scale responsively.
   • If the plugin has CSS override fields, add max-width or margin adjustments.

5. Adjust colors and text (if available)

   • Modify accompanying text, link colors, or background to match your brand.

6. Save and clear caches

   • Click Save/Apply. Clear any site cache (WP caching plugins, CDN) and browser cache to view changes.

7. Verify across pages and devices

   • Check the front end, admin dashboard, and login screen on desktop and mobile. Confirm retina/HiDPI looks fine; upload @2x images if needed.

Troubleshooting

• Logo not changing: clear all caches; ensure filenames differ from cached copies; confirm plugin is active and no theme overrides exist.
• Distorted image: set correct dimensions or enable “no-resize” option; upload higher-resolution image and use CSS to scale.
• SVG not showing: enable SVG support or convert to PNG; check user-upload MIME restrictions.
• Permissions error on upload: verify wp-content/uploads permissions (typically 755 for dirs, 644 for files).

Advanced (if plugin lacks features)

• Add CSS in Appearance → Customize → Additional CSS to target selectors and adjust size/margins.
• Replace images via child theme: copy the original image path into child theme and replace file, or use functions.php filters if available.

Rollback

• Re-upload original images or deactivate the plugin; restore from backup if needed.
