What are you submitting? Is there trailing white space or white space submitted before something?
You should probably be connecting to "example.com, username, password, sourcebans" rather than all connecting to your localhost.
Are you connecting every time for every action or connecting once and doing multiple actions?
Can you create multiple users with lower level privileges to save to the db?
I have no idea whats happening besides this error you've posted (this is not included in xampp by default) and the description of your issue is vague. The best way for us to help is to describe the steps you take to get the error so we could try and re-create it (hopefully can be solved before going this far).
Please be as descriptive as possible. What did you download/insert into xampp, What version of xampp are you using? Did you install joomla/wordpress/drupal/etc with it as well?
