For someone that using ebay module, did you ever got this error message? Please specify a query! (9003) Do not panic yet, maybe we can still solve it. This error show at the post or place that you want to show the ebay result from wprobot ebay module. No ebay product that show, but it only text like this : Please specify a query! (9003) In my experience, this error show because this ebay modul got conflict with the other plugins. In my case, i use wp-unique plugin, maybe you are using other similiar plugins. This is the problems. If i suggest you to disable this “uniquefier†plugins, maybe you will be angry with me, because this plugin is important. So, to solve this problem, all you need is “locally disable†the plugins. It means to prefent this plugin to work just on this post. For wp-unique plugin, there is option in every single post to enable or disable the uniquefier works. Try it to disable it (only in the ebay post)
