Hi! I have just installed Article Manager version 1.57_3 on a fresh copy of osCommerce v2.2 RC2. Followed the setup steps carefully and haven't done any modifications by myself yet. When opening the store from Catalog, Articles box shows Fatal error: Call to undefined function tep_has_topic_subtopics() in .../includes/boxes/articles.php on line 41 When opening the store from the Admin side, choosing Article Manager > Topics/Articles, the following occurs: Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 21911 bytes) in .../admin/includes/functions/articles.php on line 51 I'm a beginner. I've searched the forums, found similar issues, but no solutions that could help me. Any ideas, how to continue? Thanks! Rnj
