I'm using Marketpress Lite 2.5.1 on a WP 3.5.1 site in a Twenty-Ten theme.
When a user clicks a Category tag in a product listing, multiple warnings like this are thrown:
[20-Mar-2013 18:30:59] PHP Warning: in_array() [<a href='function.in-array'>function.in-array</a>]: Wrong datatype for second argument in /home/<my server user name>/public_html/wp-includes/post-template.php on line 1039
This does not occur when the user clicks Category tags in posts.
It looks like the same issue discussed here, where they say a fix was released a couple of months ago in version 2.8. It appears that is the Pro version. Is there a fix in an upcoming version of Marketpress Lite? Is there a workaround in the meantime?
