Hello,

When creating SEF URLs, parameters 'itemid' and 'Itemid' considered as different, and create a duplicate URL. For example,

Correct:
en/downloads/databases
index.php?option=com_content&catid=13&id=367&lang=en&view=article&Itemid=159

Wrong (duplicate):
en/downloads/databases
index.php?option=com_content&catid=13&id=367&itemid=159&lang=en&view=article&Itemid=159


Thanks.

Hi,

This is the correct behaviour as the variable names are case sensitive.
From my experiences the Content component does not generate links with wrong "itemid" variable, so I suppose that this link is your custom link somewhere on your website. Make sure that you use the correct variable name in your custom URLs.
