I just updated RT from 4.0.6 to 4.4.1 with success.
I now see a problem in the url encoding of “&” into “&” making the url unusable.
The base url is : https://xxxxxxxxxx.com/v3/Login.aspx?dl=0&fc=SIM_num&fv=123456789
The url is stored in the database as : <div><a href="https://xxxxxxxxxx.com/v3/Login.aspx?dl=0&fc=SIM_num&fv=123456789">https://login.oillink.ch/v3/Login.aspx?dl=0&fc=SIM_num&fv=123456789</a><br />
When clicking the link the browser is receiving the following url : https://xxxxxxxxxx.com/v3/Login.aspx?dl=0&fc=SIM_num&fv=123456789
