Hi Germi,
we're encurring a problem with two albums in music collection. Joomsef creates two different links for the same album as you can see in the following lines:

Willy Rodriguez
index.php?option=com_muscol&id=124&view=album&Itemid=2
index.php?option=com_muscol&id=124&layout=form&view=album&Itemid=2

Giusy Mercury
index.php?option=com_muscol&id=117&view=album&Itemid=2 index.php?option=com_muscol&id=117&layout=form&view=album&Itemid=2

The id is the same but one of the strings has an extra "&layout=form".

Clicking on the album you get redirected to the catalogue main page.
1) It happens just on new uploaded albums
2) If you purge URLS it starts working but just until joomsef creates the links again.

We looked everywhere but we can't find a solution to the problem.
Can you please try to give us an hand?
Thank you.
Barbara & Max
