1062 Duplicate entry 'ca34fbe5f9a075091ad59abf02c259a7-1' for key 1
in:
[INSERT INTO seo_cache (cache_id, cache_language_id, cache_name, cache_data, cache_global, cache_gzip, cache_method, cache_date, cache_expires) VALUES ('ca34fbe5f9a075091ad59abf02c259a7', '1', 'seo_urls_v2_products', /GbVE6QO7VPWmV2X+v2B7jb8RuacilmdVghNzVjNS1US7i1Pn/PhT/K4j2YLH6jlv7iYbBhjD6abt5uZMCymyYs0Bzt/wc=', '1', '1', 'EVAL', '2013-03-26 03:27:49', '2013-04-25 03:27:49')]

The above wrong code only shows one time on browser, after I upload a new product into my store. And then my website is OK if I repeat to click any page. Please anyone has ever met the same issue, or any advise regarding above wrong code. Thank you in advance.

Witch is the Zen Cart version you are using query cache?
