Nexura Upload Limits Manager – Increase Maximum Upload File Size

💡 Perfect for: WooCommerce store owners, Video/Course creators (LMS), Photographers, Bloggers, Developers, and anyone tired of WordPress upload restrictions.

• Large File Uploads: Splits big files into chunks so a single request stays under upload_max_filesize and post_max_size. The final file still has to fit on disk, and your host can block the upload for other reasons.
• Upload Resume & Retry Support: If your connection drops, Nexura will automatically retry the upload. If you need to restart the upload, it can resume compatible uploads using the same session exactly where they left off!
• Increase PHP Limits in One Click: Need to fix a quick timeout error? Easily extend your memory_limit and max_execution_time directly from the admin dashboard.
• Role & Individual Storage Quotas: Set absolute disk space limits (e.g., 500MB max storage) or single-file upload limits for specific user roles (Authors, Editors) or even custom individual users.
• Concurrent Quota Protection: Quota checks account for uploads that are still in progress, so overlapping uploads cannot skip a storage limit.
• Media Storage Analytics: A donut chart of Media Library storage, grouped as JPG, PNG, PDF, ZIP, SVG, and Others.
• Smart Garbage Collection: Automatic background cleanup of abandoned, failed, or expired upload sessions, keeping your server storage clean and optimized.
• Admin-Only Scripts: Settings and the chunk uploader load in wp-admin. The plugin does not add scripts or styles to the public site, and it does not send upload data to an external service.

1. Server Override: Where the host allows it, the plugin writes upload_max_filesize, post_max_size, memory_limit, and max_execution_time to .htaccess or .user.ini.
2. Chunked Upload: For a file above the chunk size, the browser slices it and the plugin receives each chunk, checks it against the user's quota, and stores it. After every chunk has arrived, the plugin merges the file and passes that complete file to WordPress.
3. Usage Tracking: Each attachment is recorded in nexura_upload_logs, with a short-lived cache, so quota checks do not rescan the uploads folder on every request.

• WooCommerce Store Owners: Easily import massive product CSV files or high-resolution product catalogs.
• Photographers & Videographers: Upload large RAW, PSD, or HD video files securely.
• LMS Admins (LearnDash, TutorLMS): Upload large course videos and PDF resources effortlessly.
• Developers & Agencies: Deploy large themes, plugin ZIPs, or site migration backups that exceed default limits.

1. Upload the nexura-upload-limits-manager directory to /wp-content/plugins/, or install directly from the WordPress Plugin Directory via Plugins → Add New.
2. Activate the plugin through the Plugins menu.
3. Navigate to Upload Manager in your WordPress admin sidebar.
4. Set your desired Global Upload Limit, PHP Memory Limit, and Max Execution Time.
5. Open the Role-Based Limit tab to set a quota for a role, or the User Quotas tab to set a quota for one user.
6. Simply upload your large files via the WordPress Media Library. The Chunked Engine will automatically activate for massive files!

• Fix: Media Library uploads of JPG and PNG no longer fail with "Sorry, you are not allowed to upload this file type." Chunks are assembled before WordPress checks the file.
• Fix: Plugin, theme, and block-editor uploads no longer fail with "This part is too large for the server" after the first part. WordPress was sending the chunk size as text, so later parts contained the rest of the file.

• Images, videos, and other media still upload when the host PHP limit stays at 2 MB, including uploads from the block editor.
• Theme and plugin ZIP installs are sent in small parts, then handed to the normal WordPress installer.
• The default per-file limit is 512 MB until you save a different one, so chunking is not capped by the host's 2 MB limit.
• Each upload part stays at or below 512 KB, so a 1 MB Nginx or CDN body limit does not reject the file before PHP sees it.
• A theme or plugin package that is only documentation, not an installable zip, is rejected with a clear message.
• Image processing asks WordPress for the plugin memory limit through the core image_memory_limit filter.
• Storage Usage Analysis shows the real total in MB or GB, and lists WebP, AVIF, GIF, video, and audio separately.
• Role upload limits are checked again on the server, and Default shows the current global limit.
• Plugin Check nonce, input, and short-description warnings are cleared.

• Fix: Storage quotas now apply to normal Media Library uploads, not only chunked uploads.
• Fix: Activation now creates tables and schedules cleanup and disk-alert cron events.
• Fix: Chunked uploads send the file size to the server even when the media scripts load late, and the chunk size stays under post_max_size.
• Fix: A failed merge no longer sticks the upload in processing or holds the reserved quota.
• Fix: An Unlimited role is no longer overridden by another role's numeric quota. The dashboard shows custom user quotas.
• Fix: Recalculate Storage refreshes sizes without zeroing quotas first.
• Fix: Chunk files are stored outside the web root when the system temp directory is writable, and leftover temp folders are actually deleted.
• Fix: Uninstall removes the options this plugin saves.

• Fix: Addressed an edge-case fatal error related to improper .htaccess configuration values when selecting "Unlimited" upload size.
• Fix: Resolved a "headers already sent" PHP warning triggered under specific server conditions during background storage calculations.
• Enhancement: Hardened UI logic for safer limits modifications.

• Feature: Introduced the Smart Chunked Upload Engine. Helps work around per-request server upload limits by securely splitting and merging large files.
• Feature: Implemented True Deterministic Upload Resume and Network Retry mechanics (resume instantly even after page reloads).
• Feature: Added Database-level duplicate chunk protection (nexura_upload_chunks) to mathematically prevent concurrent chunk race conditions.
• Feature: Added Concurrent Quota Protection to prevent malicious users from bypassing their storage limits during multi-file uploads.
