I am having a wierd error on my site. Nothing visual though. Causing a problem with a plugin. When I visit my site (tested on multiple sites however), WP is actually loading my theme several times in the background before displaying. For example, if I add a PHP mail function call in the header file, sending an email to myself, then refresh my site, I will receive 7 emails. When I should only receive 1. ??? Is there any reason for this? Does WP do something that I am unaware of?
