    Hi devs and plugin-users,
    does someone have a solution for the “224” error?

    ]-->
Warning: Invalid argument supplied for foreach() in /home/content/p3nexnas05_data03/63/2131563/html/wp-content/plugins/amazon-product-in-a-post-plugin/inc/amazon-product-in-a-post-shortcodes.php on line 224

    As far as I understand it, it’s because there are too many requests to the AP API.

    I’ve different pages, e.g. https://www.brettspiel-k?nig.de/auszeichnungen/graf-ludo/
    Here I wanted to show images (left side) to all board games (right side). I do this with this in one call:
    [amazon-element asin="B00AOZVL0E,B0088UZZJK,B006Y9K3R6,B006BJAYQ4,B003R1YV40,B004H7RM4O,B002GYV9OE,B0037LRUMU,B001TLTYPQ,B001QTPCVQ" fields="bk-award-list-med-image"]
    Before I made unique calls for every displayed game. Then there were like 5 out of 10 images shown. With the new code (1 “amazon-element” with all games) it works from time to time. But other times, there are only a few images show or even none.

    I don’t know how the caching works in details or if there’s another way to optimize my requests? Please advise, thanks.
    Two ideas:
    – If such an “amazon-elements” shortcode is used with multiple ASINs, wouldn’t it make sense to automatically delay each requests by a small time amount?
    – Also wouldn’t it make sense if the cache automatically refreshes? I mean if 60 mins for an ASIN is over, just make a new request.

    Hi there,
    I could solve the issue a few days after I opened this topic. The problem was that the ASIN had an additional “code” tag and therefore wasn’t valid.
    The problem is you only see this in the “Text” editor not the “Visual” editor of wordpress.
    A wrong entry looks something like this:
    [amazon-element asin="<code>B009CQLZR0</code>" fields="bk-full-image"]

    You can also see the error on the Product Cache page of the plugin. A wrong entry looks like #97 in the following screenshot:

    I can’t say where the “code” blocks came from, but removing them resolved the issue. If you have a problem, double-check your code in the “Text” Editor and have a look at the Product Cache.
    Cheers
