=== Error ===
Request ID: `INSERT_ID`
- Installed TinyMCE-0.2 on mediawiki-1.31.1.
- **User language is set to 'de-Deutsch'.**
- Uploaded a file (without TinyMCE) 'Osmbanner2.png'
- Clicked button 'Upload/edit file' in TinyMCE.
- Select: 'Upload type' : 'File in this wiki'.
- Enter 'Osmbanner2.png' in field 'Source filename'.
- Leave the field: You get an error from mw_upload/plugin.js line 319 because `destinationFileDetails` is empty:
```
tinymce-upload-confirm-file-not-on-wiki
```
Reason: In line 159 of plugins/mw_upload/plugin.js there is a comparison check
```
if (pageTitle.replace(/_/g," ").toLowerCase() == fileName.replace(/_/g," ").toLowerCase()) {
fileDetails = imageURL;
}
```
`pageTitle` is '**Datei**:Osmbanner2.png' (German).
but
`fileName` is '**File**:Osmbanner2.png' (English).
So `fileDetails` is always empty.
