Thanks, turning off Rocket loader seems to have done the trick.
However I have a couple of other questions about the search – when I type in a location like Sydney in to the “Near” box, listings in Sydney will come up, but when I search for the location Melbourne, there are no results, even though there are listings in Melbourne, and with the word “Melbourne” in the listing title.
Also the compass icon has disappeared, in the console I have the error
Uncaught ReferenceError: geodir_insert_compass is not defined
When you enter a search term and the results come up, the search term appears in a box with an X which gives the impression you can click the X to remove the search term, but nothing happens when you click it?
And finally, with the location search, results are listed from nearest to farthest, is it possible to have the featured listings appear at the top even if they are further away?
