Drupal 7 Update Manager not working Update manager takes me to the page where I select the checkbox for the updates I need. I check the box of the module and then it downloads the update. After the download it tells me I should put my site in maintenance mode with a checkbox that is on by default. The button says "Continue" to install the updated module.

My problem lies after this point. No updates are installed and after clicking "Continue" I get booted to my home page with the message "Operating in maintenance mode. Go online."

So currently the only way to update my modules is manually. Update manager doesn't work for me. Any pointers as to why it behaves the way it does?
Does yoursitename.something/update.php runs after you put it your browser location.
I can only guess maybe your site hosting space is full or you might not have given update permission to the role by which you are updating the site.
