There are similar questions here but they have not the answer to my problem.
My app folder is below dev/, so I put the line
Configure::write('App.base', '/');
in the bootstrap.php to get the links work without 'dev' in the url.
But in one form I refer to $this->here as the action and it has an extra slash at the begining like //admin/controller...
How can I avoid the extra slash?
Configure::write('App.base', '');
I actually stumbled upon your (old) question while trying to fix some $this->here issues on a shared host, and your question actually helped me solve my problem. So, thanks.
But in case you're still looking for an answer a year later, the above works.
