I am writing a jQuery Translation Plugin. My first iteration passed an array of strings to translate. Although this worked fine, it was dreadfully slow. I modified the plugin to pass a single word at a time. Both routines use ajax to call the PHP Translate function shown below. I have checked to ensure the ajax calls are working and properly passing the words. I have also checked answers relating to the warnings to no avail.
After the first word is translated, I get the following messages that repeat for each word. I also get a couple of curl errors complaining it could not connect to host (Translate-Exception: curl=couldn't connect to host) after numerous warnings.
Warnings
Startseite (the first word is translated correctly)

It seems there is some kind of timing issue, but I cannot identify it. Hopefully someone out there has experienced a similar problem and can shed some light on this painful situation.
