It looks like you fixed this, but for the sake of completion I am guessing you opted in Better WP Security to rename wp-contents.
This adds two constants to wp-config which contain the path to the renamed folder on the server. Find out the new server path and replace it and it will all come back to life.
Worked brilliantly, thanks. Problem solved.
I think I have the solution to this for you – even through it may seem a little late others searching for the issue who find this may be helped.
The issue does lie in the php.ini file, but in two places.1
upload_max_filesize
and
post_max_size
Increase these both and you should be right.
