Takes long time to send message after pressing the enter key.

When I press the enter key it takes a long time for the message to send. Like 3 minutes. I am using the GridMarket theme, membership Plugin, and MarketPress plugin. My webhosting is bounceweb. Also after message is send you can not use the bottom right chat button. What dO i need to do. I have deactivated all plugins and used the default theme but still having problem.
