Unique expression of a polynomial under quotient mapping?

You can save credentials. If you save the connection as an RPD file, and use that file to initiate the connection, you can specify in options for the connection "Allow me to save credentials". It will prompt you the first time then shouldn't afterwards. It's possible your domain is set up in such a way that you can't save the credentials at all.

Corrupted gems have to be "charged", to charge a gem, keep killing monsters with it equipped (not in your secondary weapon slot though).

They work like potions, in that you can use them after killing enough monsters to recharge them.

As stated in a comment, your get_posts parameters are wrong. There is no such parameter as term_id. You should make use tag which uses the tag slugs as a string or tag__in which uses the tag ids in an array

This will work

$posts = get_posts('numberposts=6&tag='. $tags->slug);

or this will work

$posts = get_posts('numberposts=6&tag__in=' . array( $tags->term_id ));

There are some other issues as well that I want to highlight here

• You should set the post ID in get_the_tags(). Do something like this get_the_tags( $post->ID );

• Set the plural name as the variable name which will hold your array from your function and use the single name as your value in your foreach loop. This eliminates confusion and is easier to debug. If you read this, $tags->name, you immediately think of more than one tag, yet this is used to retrieve the specific tag's name as $tags are actually your value. You should do something like this which IMO is far better to understand and less confusing

  $tags = get_the_tags();
  foreach ( $tags as $tag ){
      echo $tag->name;
  }
  

EDIT

To exclude the current post, you can do the following

$posts = get_posts('numberposts=6&tag__in=' . array( $tags->term_id ) . '&post__not_in=' . array( $post->ID) );
