I've been using Plusnet ADSL for about the last month and been very pleased with the connection speeds etc.
Recently I tried to upload some files to my yahoo webspace, using their web page based file manager, I have found I always get a page not found error when trying to do this. It is also the same on other websites when trying to upload via a webpage.
It used to work no problem with my old dial up modem connection, but now it no longer works either with a modem or ADSL.
The only other software I have installed since upgrading to ADSL is ZONEALARM. Would this stop it working? But even if I disable ZONEALARM it still is the same.
