The offer for help was that I give full access to my system, which is a security issue for me, and I think the issue may be SSL related, but I am not sure.
It is a pity to hear you did not get it work. There are instructions, faqs and contacts possibilities on our site and instruction videos on You Tube. This component is a STAND ALONE extension (no need of any other software), which can be used if you put in the right settings. These settings are a "Vtiger Portal Server Path", "Character Set" and if you like to see the portal without registering in Joomla or not. We are at all time available to help our customers, and sometimes we need to see things in the working settings, and therefor we ask credentials to see what is happening and to correct wrong settings inside the options/settings. If your vtiger installation works and the portal from vtiger is working then most likely our component will also. Hope to hear from you so we can help to solve this problem.
