All files corrupted after download

[Arno]

Thanks for the update and your offer to help.

At this point this looks like an environment-specific edge case in the PHP download stream path (Chromium strictness with partial/range validation), not a general frontend issue.

I will send you a dedicated test build via PM. This test build temporarily disables resume/range handling in the PHP download path to isolate Chromium/proxy partial-content issues.

Please test with the same file in Chrome and Firefox and report only:
1. file size after download (both browsers)
2. whether the file opens correctly
3. whether direct download mode (without PHP script) works on your site
