The following is the error I get:
A File Error has Occurred
There was a problem when CATS attempted to process the file you selected. File size is less than 1 byte. File errors are sometimes caused by high Internet traffic or older web browsers. The latest version of the Mozilla Firefox© browser is recommended.
The problem may be resolved by using the back button on your browser and trying again.
I have tried multiple times including on firefox. I have also gone to my hosting provider and they were unable to help, but they ensured the php.ini file values were all correct. Can anyone help me?
