I have a logo that just will not upload through the Media Manager in Joomla 3.1 For some reason the minute I click the Start Upload button the screen goes blank and white. Nothing gets uploaded. I just wondered if something like antivirus would block that or if there is a problem with Joomla 3.1 I do not know about. It is strange as it has worked before now it will not. The only thing that I see that has changed on this machine is the Anti-Virus. I have never known AV to stop an upload when all my FTP stuff works just fine.
