Though this is not directly related to admin tools
but you been a super expert in joomla - may guide
i have just ugraded my joomla 2.5 site to joomla 3.6.2 with php version updated to 5.6.x latest series
However - while submitting url index to google - i observed that in headers it shows a concern about expires date pertaining to august 2005
I checked all previous url in joomla 2.5 - there it was no expires date mentioned
Searched google and found that joomla.org even has this expires header
I do not know if its a bug pertaining to joomla itself
But i dont want any negative impact on site related to site ranking,
If can suggest basis expertise - why this expires header been kept of 10 year old date and can it impact site negatively in search engine due to it as header
If yes - you feel a impact - is there a suggestion on how to remove this expires header
Many thanks for been a God in Joomla community for class leading safety extension as built by you !!
