I am not sure if this is an offshoot of a recent update of the Avast Internet Security.
But whenever I keep uploading my message to the website I’m working on, it keeps getting a Not Found page for at least five tries, but eventually the message will upload to the server of the company I’m working with on the sixth or after several attempts of hitting the submit button.
Please see attachment for the web page (Not Found).
This is normally a error/problem on the server/site.
Without more information there isn’t really anything to say about the problem.
A thing you can try is disabling the avast shields one at a time and see if it makes a difference.
If the site is using https, you can also disable the https scanning in avast to see if it makes a difference.
Thank you for the information you provided. I got with the website administrator I’m working for, and he fixed the bug on the server that I was having problems uploading files (based on your tip, by the way). So thank you again.
