Fixed path to subdirectory
Allow settings changes only on first install or if user authenticated
Added whole page caching, cache invalidation on new post, cache action added to dashboard
Fixed main page caching, It seems the buffer didnt collect everything so it saved an empty cache file
Fixed 404 caching and single page caching. Should be working 100% now.
My bad, forgot to add If index cache exists, serve it directly.
Caching fixed finally
