OK so I am on 3.4.2 using a modified default theme (tweaked colors changed layout etc)
I am experiencing a problem very similar to this thread
difference, it doesn't do anything, it enables maintainance mode and then hangs pretty much with the little 'spinning icon' going and going in circles.
I end up throwing my hands in the air a minute later saying the hell with it logging into FTP and deleting the .maintainance file.
this is pretty unnerving, especially with the 3.5 update banner looming... do i really want to do THAT big of an update with it not even successfully completing little plugins... um.... NO.
Posting works fine, all other functions seem to work fine, but when I get to updating anything, forget it.
PHP is - PHP 5.3.19
