Hi!<\/p>\n

I am struggling with a feature in the Optimizer theme free version.<\/p>\n

In this feature:
\n“Display posts from these categories only”
\n– You can select a item (category) to only view those posts.<\/p>\n

if(!empty($optimizer[‘posts_cat_id’])){
\n\t\t\t$postcat = $optimizer[‘posts_cat_id’];
\n\t\t\tset_query_var( ‘cat’, ”.implode(‘,’, $postcat).” );
\n}<\/p>\n

I get this warning:
\n– Warning: implode(): Invalid arguments passed in themes\/optimizer\/lib\/functions\/core.php on line 25<\/p>\n

Line 25 is – set_query_var( ‘cat’, ”.implode(‘,’, $postcat).” );<\/p>\n
