Upgrading Drupal

I installed the DRUPAL-SA-2006-001 security patch this morning to my 4.6.5 site. When the menu cache was regenerated this evening, some of my menu items disappeared. I temporarily disabled menu caching, and rolled back the patch, and the menus reappeared.

I see that the patch removed a bit of code that set this "access" variable to true for items that were "MENU_CREATED_BY_ADMIN". I assume that the patch is doing the right thing, so I'm assuming that my menus were somehow misconfigured to be admin menus. But, I can't, for the life of me, figure out where this setting might be.

Is it possible to find out the current version of my drupal install without the changelog.txt

Ok, I think i deleted my changelog.txt, now I am not sure my version of drupal I had installed. Is there an alternative way to find out?

I have not been able to successfully upgrade a Site5 Fantastico (scripted install) drupal 4.6.5 intall to a 4.7 beta6 install. I have a request into site5 to find out if their Fantastico version has any unique characteristics that would make this a problem. However it is likely I am simply not understanding something clearly regarding the upgrade process. I have searched this site and read the upgrade instructions.

I've restored a data backup on my site and found a rare behavior with the characters Á and Í: all ran out.
When I try to send them, I can see them in preview mode, but when upped, they dissapear.
¿Anybody knows what's the matter?

Not feeling particularily adventerous, I thought I'd ask before going ahead.

I found instructions for how to upgrade from 4.6.3 to 4.6.6 and was wondering if it's the same route to take from 4.6.2? Or must I take an additional step between 4.6.2 up to 4.6.3 before following those instructions?

I apparantly missed something along the way, by ways of security patches and whatnot... *kicking herself* Thanks for any advice you can offer up!

The i18n patches don't work with 4.6.6 core! Users of multilingual sites have to patch the core files manual.
