Switch on Debugging
Hopefully you will get a message, and/or something will be logged in your web server's error log.
Try clearing Moodle cache via direct URL:
http://yoursite/[moodle]/admin/purgecaches.php
or from command line:
cd moodlecode/admin/cli/
php purge_caches.php
If neither of those work, time to get 'nasty' ...
cd pathtomoodledata/cache/
manually remove all in that direttory:
rm -fR *
The cache will be rebuilt as one navigates the site via browser.
If none of that works, turn on debugging via direct URL:
http://yoursite/admin/settings.php?section=debugging
Could also turn on debugging by copying appropriate lines from config-dist.php to config.php for debugging.

Thank you both
Ken, I did everything that you wrote (including removing all what's in cache folder) but still same problem.
Purge cach didn't work too
debugging is on gives this message:
Fatal error: Nesting level too deep - recursive dependency? in /var/www/html/moodle3/lib/coursecatlib.php on line 235
Any ideas?
Thanks
Check Apache error logs for clue.
Check php config for 'max' and see if there is a setting for max_input_nesting_level
If there is not a max_input nesting level line in php.ini add one:
max_input_nesting_level = 500;
The value is a guess. Restart apache service.
Oherwise, congrats! You may have discovered a bug! After all, it's .0 :| Might be fixed in 3.0.highest!
from code directory as root:
git pull
php admin/cli/upgrade.php --non-interactive [ENTER]
chown apache:apache * -R (assumes RH/CentOS ... change user:group to suit).
If that doesn't fix ... probably need to provide more info about system.

Thanks ken, it's seems like it works I don't get the error anymore.
I updated the max_input_nesting_level 500
if I see it again I'll write here again , but it seems good now.
Thanks you.
p.s the php version in the server is 5.4.26 is that was the problem?
Not sure that the version of PHP was the cause. More than likely, the organization of categories/subcategories in the Moodle that might require 'deeper' nesting query (that's a guess). The minimum requirements for running a 3.x is PHP 5.4.4 according to release notes.
I've some Moodles running 5.4.x (I think) and have not had to make that change ... but then again, they don't have 50 categories with 10-30 sub-categories either! ;)
