Hi,
I'm using the Query String Filter web part to filter a couple libraries on a page, and using the query URLs in the quick launch navigation. For the most part this works fine and there is no issue, but on some occasions the query string is doubled after applying the navigation changes.
i.e. - /sitename/pages/pagename.aspx?query=example
becomes
/sitename/pages/pagename.aspx?query=example?query=example
Usually I just wait a bit and try again and the issue seems to resolve itself, but wanted to check and see if there was a better fix.
Thanks
