Post installation

Due to constraints of my hosting company, I have installed an older version drupal 4.5.2 for my site. as this is my first experience with drupal and i went on to explore the various settings as the administrator of the site. I suddenly discovered that the menu item "access control" underneath the administer menu item is missing. I have installed comments, forums, archives, polls as extras (if you'd like to call them that).
All searches return forum topics that show how to do some work inside administer>>access control. but in my case i don't have that link only.

In i18n 4.7, what is the difference between the language switcher versus translations blocks?

hello,
i need to implement Drupal so that when an anonymous user visit my site she/he can view normal pages, if log in can see a block with latest calendar events.

i tryied in this way:
enable taxonomy
install taxonomy_block
install tac_lite (Taxonomy Access Control Lite, Taxonomy Access Control is the same)

but i get too much MySQL errors i can't solve otherwise

somebody had some other ways to do this?

I just upgraded my site from 4.6 to 4.6.8 and added the image module. I enabled the module and set admin to have access control. The module appears under the settings node, but when I click on it, it just displays the text "Array" and then the save and restore buttons. The same happens under the image gallery node too. If I click on the image galleries node under administer, I just get a blank page.

Anyone know what could be wrong?

I would like to use special formatting in my drupal posts, but when I try, they always turn out looking bad. For instance, I tried making an FAQ and after each question or answer I would hit enter to go to the next line, and it all looked fine, but when I submitted it, everything became one big continuous paragraph. I have tried TinyMCE, but I can't indent lines in it and some of my formatting gets discarded.

On the following link you can see a row of images. These images are in a table and were added with tinyMCE and img_assist. Behind each image a space and an CR is enterend automaticly. How do I prevent this behavior?
