Premature end of script headers

Coding Issue: You have an extra space or carriage return in your coding after the closing of the ?php tag.

Your script has exceeded resource usage limits. This can occur if your script is using over 128MBs in a single process. After the 128MB the process is killed due to excessive resource usage which results in the internal server error and a premature end of script headers listing in the error logs. To prevent this from occurring you will want to optimize your coding to be more efficient and use less memory via optimization, reducing features, pruning databases, or upgrading your plan to a plan better suited to the high memory demands your account requires such as the semi-dedicated plan or higher.
