Incredibly outdated features

Subject: Critical Bug: ProfileGrid Avatar Upload (crop.php) Incompatibility with WEBP and AVIF Formats

To: ProfileGrid Support Team

Hello ProfileGrid Support Team,

We are using your ProfileGrid plugin on our project and are very satisfied with its features. However, we have encountered a critical incompatibility issue that makes it impossible to use the plugin on any modern, optimized WordPress site.

The Core Problem:

Your user avatar upload script (/public/partials/crop.php) is completely incompatible with modern image formats like WEBP and AVIF.

On any site using an optimization plugin (in our case ASE Pro, but this applies to any: Converter for Media, Imagify, etc.) that converts images to WEBP or AVIF during the upload process, the avatar upload in ProfileGrid breaks completely.

Technical Details:

We have conducted a deep debugging session and identified the root of the problem:

1. Custom Uploader: The crop.php script uses an old, custom method to process $_FILES['photoimg'] (line 8) instead of relying on the modern WordPress media library.
2. Hardcoded Extension Filter: The script has a hardcoded allow-list: $allowed_ext ='jpg|jpeg|png|gif';. This prevents .webp or .avif files from passing validation.
3. Processing Failure: Even if we modify that line to include webp and avif, the script still fails at the processing stage ($image->crop(...)) because the wp_get_image_editor (in the context of this legacy script) cannot correctly process and crop these formats.

As a result, when an optimization plugin intercepts the upload to convert it to WEBP/AVIF, the crop.php script either receives nothing (triggering the PHP Warning: Undefined array key "photoimg") or receives a file it cannot process.

Our Request:

Since modern formats (WEBP, AVIF) are now the de-facto standard for performance and SEO, this issue is a major blocker.

Could you please update the crop.php script (and any other custom uploaders in your plugin) to use the modern WordPress core functions for media handling (like wp_handle_upload)?

This would automatically resolve all issues with WEBP, AVIF, and other future formats by leveraging the WordPress core, which has natively supported them since version 5.8.

Our Environment:

• WordPress: (Latest Version)
• PHP: 8.3

Thank you for your time and for a great plugin. We look forward to an update that resolves this issue.

Sincerely, Aksel
