The proper way to accomplish this is not to strip links from $post as you may want to customize the posting template to include links of your own.
What should be done is insert this code:
PHP:
$textc = preg_replace('%</?a\b[^>]*>%i', '', $textc);
$authorbox = preg_replace('%</?a\b[^>]*>%i', '', $authorbox);
$keyword2 = preg_replace('%</?a\b[^>]*>%i', '', $keyword2);
For WPRobot 2.11
right below:
PHP:
$post = get_option( 'ma_eza_template'); //'{thumbnail}{description}{link}');;
For WPRobot 2.12
right below:
PHP:
$content = get_option( 'ma_eza_template'); //'{thumbnail}{description}{link}');;
This will only remove links from the article, while leaving the links in your posting template (that you might have added yourself) intact.
