Hello there,
Currently I'm migrating confluence/wiki system from Confluence 3.5.13 to 4.3.7, but during the migration, I came across a problem. I customized a search function in our confluence space with Advanced Search plugin, I have used {search-form},{search-input},{search-select},{search-option} and {search-results} to customize this feature. But the search result can not be shown, just like the attached capture shown.

I found from Atlassian marketplace that the plugin vendor can only support till Confluence 4.2.1,

So do that mean the plugin is not compatible with Confluence 4.3.7, and that's the reason why the search result can not be shown on page? Hope someone may help.
Thanks in advance.
Best Regards
Li
