Hi, it's me again. Hope everything goes well.

Problem Summary

FoF Upload appears to be perfectly installed but cannot be activated in the Admin panel, and when manually enabled via database, it shows "File type not allowed" errors.

_Technical Environment
Flarum Version: 1.8.4

FoF Upload Version: 1.8.4

Hosting: Hostinger Shared Hosting

PHP: 8.1+

Structure: Mixed public_html with assets in root_

What WORKS ✅

# Images are physically stored and accessible
ls -la assets/files/
# Output: Directories with dated images

# URLs are accessible via direct links
curl -I https://fictograma.com/assets/files/2025-10-20/1760963059-432467-ai-generated-8891427-960-720.jpg
# HTTP/2 200 - Image loads perfectly

# External image links work in Flarum Discussion Cards

What DOESN'T WORK ❌
❌ FoF Upload cannot be activated in Admin panel

❌ When manually enabled via DB, shows "No se permite subir archivos de este tipo"

❌ FoF User Bio profile images don't display

❌ Any feature depending on FoF Upload fails

Database Configuration

-- Manual activation attempted
UPDATE fg_settings SET value = '["...","fof-upload"]' WHERE `key` = 'extensions_enabled';

The Core Problem

Despite perfect technical installation, FoF Upload has fundamental compatibility issues with this specific server configuration. The extension loads but cannot initialize properly.

Attempted Solutions (All Failed)
✅ Complete reinstall (composer remove fof/upload && composer require fof/upload)

✅ Database cleanup (removed all fof-upload.% settings)

✅ Cache clearing (rm -rf storage/cache/*)

✅ Autoload regeneration (composer dump-autoload --optimize)

✅ Permission fixes (chmod 755 storage/private-shared/files)

✅ MIME type configuration variations

Workaround Solution
Using external image hosting services:

Users upload to Imgur, PostImage, etc.

Paste direct links in posts

Flarum Discussion Cards works perfectly with external image links

Less technical overhead

Questions for Flarum Community
Has anyone experienced similar FoF Upload activation issues on Hostinger?

Are there known compatibility issues with mixed directory structures?

Any alternative upload extensions that work where FoF Upload fails?

How to debug why an extension installs but won't activate?

Current Status
The forum functions perfectly except for native file uploads. External image links provide adequate functionality with Flarum Discussion Cards working as expected.

Migration Background
Before Migration:

✅ Subdomain: forograma.fictograma.com with FoF Upload WORKING

✅ Location: /home/u148719152/domains/fictograma.com/public_html/forograma/

✅ FoF Upload: Fully functional on subdomain

After Migration:

✅ New Domain: fictograma.com (main domain)

❌ FoF Upload: Stopped working immediately after migration

✅ Other Features: All other Flarum functions work perfectly

Migration Process Used

 1. Copied Flarum files from subdomain to main domain
cp -r forograma/public/* ./
cp -r forograma/vendor ./
cp -r forograma/storage ./

 2. Updated config.php
'url' => 'https://fictograma.com',

 3. Created .htaccess in old subdomain to redirect
echo "RewriteEngine On" > forograma/.htaccess
echo "RewriteRule ^(.*)$ https://fictograma.com/\$1 [R=301,L]" >> forograma/.htaccess

The Critical Clue
FoF Upload worked perfectly on the subdomain but broke immediately when moved to the main domain, suggesting:

Path-related issues in FoF Upload configuration

Database references still pointing to old subdomain paths

Cached configuration from the subdomain installation

Permission inheritance problems during migration

Additional Diagnostic Info
The mixed directory structure (some files in root, some in public/) might be a result of the migration process rather than the original installation method.

Current Theory
The migration from subdomain to main domain created path resolution conflicts that FoF Upload cannot handle, while other Flarum components adapted successfully.

The problem is likely in FoF Upload's path handling during domain changes, not in the basic installation or server configuration.
