I have strange .htaccess File in my Templates Folder that just seems to have appeared, sure it was not there before. Does anyone know what it is for and why it may have just appeared?

It only contents is:

deny from all

Hey MarkerMaker,

Thank you for posting your question here on the ExpressionEngine forums.

This is normal. It just keeps that directory from being browsed.

If you need anything else, please just let me know by opening a new thread.

Cheers,
