Upload error 302 - mp3 and additional files

I can ftp the files to calvary.org.uk/sermons but the upload isn't working for either the sermon upload or the additional files upload I get
Upload error: 302

Help!

I've spoken to Siteground our host and they say there's no limits in .htaccess, or PHP/Joomla that should cause this.

If you email me I'll send you login details.

302 usually means that there is a redirect somehow happening.
If you want to send me the credentials, you can either use the contact form or my email bakual@bakual.ch

The uploading is redirected to this page: calvary.org.uk/mod_sec.html
So it looks like a server setting. Mod Security can have various rules. It's hard to say what exactly is triggering it

FIXED!

For info I was able to disable the re-direct by putting this into .htaccess

<IfModule mod_security.c>
# Turn the filtering engine On or Off
SecFilterEngine Off
</IfModule>

Thanks for you help

Now to my next problem. The file upload limit!

Most of our sermons are 50Mb - 100Mb,

I've tried putting
Max_upload_limit to 250 in php.ini in (various places!)

Any thoughts appreciated.

Try this.
upload_max_filesize=300M
I wouldn't disable whole engine, though it it's a useful mod, i'd find out which part of it is giving you issues.
