PHP – invalid request (unexpected eof)

I was receiving this error from a php internal server while developing and testing. I found this StackExchange post in which I found a comment that this is caused by empty <script ...></script> text I then searched for </script> at the RootDirectory and found wp-admin/about.php @ line 55 contained the above occurrence. I modified this to remove the </script> and use <script ... /> form instead. This caused the invalid request to not be given and speeded up the page resolution.
