It looks like there are two issues here:
(1) The set_time_limit() warning
(2) The layout of the admin 'Pages' page
(1) It looks like your web host has disabled set_time_limit(). This is unlikely to cause any problems (unless you have a very large site with lots of images and your web server's default time limit is too short for Showkase to process everything when you re-publish, in which case you will not be able to increase the time limit). However, this may never actually cause you any real problems. (You could, however, ask your web host to enable set_time_limit() on your hosting account and see what they say.)
(2) Your 'Pages' page layout is set by CSS code in the 'showkase/admin/css/all.css' file. Please double-check that the 'all.css' file is present in its correct location on your web server and that it is not corrupt or incomplete.
Also, try clearing your browser's cache before reloading your 'Pages' page to see if this helps.
You could also try viewing your 'Pages' page in a different browser to see if this makes a difference.
If you continue to experience difficulties, I would be happy to help further but I'd really need access to your web server and Showkase site to check things out.
If you are agreeable to this, then please let me know and I'll send you an email address where you can forward me your FTP and Showkase login details.
Once I'm able to see the problem for myself, I should hopefully be able to determine the cause and propose a solution.
Thank you.
