I have a GHL stand alone doser 2.1, it works great. However I tried to log in to change my dosing rates. However the dosing pumps to not show up when I login. the doser is showing that it is on line however I can't see the pumps so that I can make adjustments such as fill level etc. I noticed the page is slow loading. So I tried to work with it from work and I get the same results. Thanks in advance for your help.
