Notification from forum with variable names instead of valid url and thread title

[alexpilion]

Hello there, just wondering is this an issue of my mail service provider or related to the email template? 
Sso everyone is not receiving anymore the properly formatted URL among the Notification mesage from forum activity which is showing a kind of scripting variable name.

See the screenshot below.

Greetings,

My forum notifications appear normal with correct formatting, variables and text display.

I don't currently have any subscribed topics (like yourself), but others look normal.

The buttons on my Canoscan 9000F Mark ii stopped working.  If I open the Canon IJ scan utility on my computer, all the functins work.  When a buttn is ushed the on/off button lights, but the scanner does not operate.  What might be wrong?  I have not tried tried downloading the driver of which there are two possibilities.
