Hi, we use hotspots to display various medical centers on our homepage. Both the charge time of the card, but especially the charging time of the short descriptions next to the card is extremely long. In the demo on your side, however, the charging time is very short. At the DSL speed it can not be so ever.
The site actually shows a 500 internal server error for the request that loads the hotspots. How many locations do you have in the database? Dop you have the "use content plugins" option set to yes or no in the configuration?
