After upgrading from 4.6.x to 4.7.4, my site has "lost" the administer >> access control item. I don't see any error messages or indication why it's gone. I have a (separately built) 4.7.4 site on my local computer that does have it so I think it should be there. What did I do and how do I get it back?

I upgraded using Fantastico on my webhosts cpanel page. I didn't see any errors in the upgrade process.

I'm just curious how you can get drupal to reinstall a module manually.
I had some problems upgrading the organic groups module to the 5.0 version, it was hanging on the update.php,
so I decided to drop the tables manually, but now when i check or uncheck the module it just errors out saying that the tables do not exist.

i just upgraded my site from 4.6 to 4.7 and I get a blank page on any forums and under admin -> comments. Also if I run cron.php it indexs 5% of the site and then logs me out. Under Admin -> access control i get "admin/access denied access". I disabled all noncore modules before installing and there are no 4.6 modules in the module folder. I'm running an Apache server with PHP 5.2. Any ideas?

Hi,

I am runnig a drupal (4.7.4) powerd site on an hosted enviroment. Everything worked fine on PHP 5.2 and Mysql 3.x (Don't now the exat version anymore). Yesterday my Host upgradet to Mysql 5.0.27 and I have 2 Problems:

1. All specialchars (ä, ö, ü, ß...) are wrong. They are even wron in Databaseview of PHPmyAdmin and I can't display them right iv I change Collation to UFT8.

2. I can login to my site but after login it seams that i get kicked of when navigating to another page.

Is there any way to restore the specialchars and to get Login working again?

I have a problem which occurs generally with non-European languages, especially Russian and Bengali. Presumably because in Unicode a lot of the characters are two-byte (and in the Indic scripts also, a lot of "characters" are actually working to modify adjacent characters, rather like accents in European languages), I often find that the node title is too short to contain the titles that I want for articles.
