v151 Template Selection not saved

Hello!

I am not sure whether it is a bug or just me(my server), but in my installation of 1.5.1, the template selection is not saved. It resets to nothing every time I check(Tools -> Template Selection -> Edit -> Update)

It is a completely new installation of Zen Cart 1.5.1, with no changes.

We need more info that is requested in the posting tips.
Please answer as many as you can especially as to whether or not this was an upgrade AND do you use a script to get where you are at this point.

No, it was not an upgrade, as I said, it occurs on a new Zen Cart 1.5.1 installation, which I installed myself without any scripts. I just changes back to

Template Language Template Name Template Directory Action
Default(All)

whenever I change templates, however if I write it directly in PhpMyAdmin it remains(until I change it again in admin panel)

I just did a fresh brand new installation of v1.5.1, then added another template. When I go to the Template Select screen, it saves my changes fine. I can swap back and forth between templates by choosing the template and saving it. And then see it on the front-end. And change it again in the admin, and the changes show on the front end again.

Then I guess it has something to do with my server, but it is okay, as I can always write it directly in PhpMyadmin and do not change templates that often.
Thanks!

Something has to be missing, incorrectly placed, or FTPed incorrectly in order for this not to work.

You still haven't told us things that would help (those pesky posting tips) like what mods you are using. It would also help to know which template you are using.

Meanwhile, have you looked at http://www.zen-cart.com/content.php?228-understanding-the-override-system and its subordinate links. You'll find that some files are required to be in the correct place or the template is not going to work correctly.
