• Consistency

I got a problem to see thumbnail and download file from File Gallery.
What I did are:
1. create a customized a folder for file gallery
2. point the file gallery folder destination to the new folder in setting.
3. upload a file
4. try to view the file and download the file, the system goes to endless loop, and no responds from server to client, logs are continuously generated till disk full.

5. after I check the code. in the tiki/tiki-download_file.php, line 146, it has below
while (ob_get_level()) {
ob_end_clean();
}// Be sure output buffering is turned off

6. I googled the coding, looks it should be changed as below.
while (ob_get_level()>1) {
ob_end_clean();
}// Be sure output buffering is turned off

7. I changed, the code, the file viewing and download are perfect. problem is solved.

Could any developer please review the code, if it is the way to go, please merge the change into the main trunk for future releases.

Thanks.
