Can't get Autocomplete to work

Reopening because I still have this problem. Is it possible the autocomplete is not working because it has problems with the domain it's on?

I'm developing a site on the address website.synology.me:8888/website.be/www/nl/. The input element has this attribute:

data-autocomplete-path="/website.be/www/nl/search_api_autocomplete/zoeken?display=block_search_products&&filter=search"

The url "http://website.synology.me:8888/website.be/www/nl/search_api_autocomplet..." works fine, but maybe the relative path resolves to "http://website.synology.me/website.be/www/nl/search_api_autocomplete/zoe...", which isn't working. Or doesn't that make any sense?

The thing is: the autocomplete does work in the views preview, but not on the actual page.

Hm, unfortunate if this problem apparently still happens, at least in certain cases. (Does not seem very wide-spread, luckily.)

No, at least in my browser (Firefox) this seems to work as expected. When you have a link <a href="/foo">foo</a> and are on the address http://domain:8888/bar/foobar, then the link will take you to http://domain:8888/foo, including the correct port. (Which is, I think, what you meant?)

I suspect you have tested with the latest version of the module? Adapting the “Version” field accordingly.
