leradstar on "Admin rights disabled after moving site to new host"

Hi,

I've moved my site, something I've done many times but this time on database import I encountered some problems one which is listed below
The site is operational but I cannot save or publish anymore. The textblock is no longer visible and the ability to add images.
I've tried switching to a default theme, disabling all plugins and using the default theme only. I don't know my way around MySQL and I've read elsewhere that I need to create wp_user_roles in the wp_options table.
Also I need to say I have debugged WP, optimised and repaired the database and nothing works.
Error with database import:

MySQL said: Documentation
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DROP TABLE IF EXISTS wp_my_calendar_categories;
CREATE TABLE IF NOT EXISTS `wp' at line 13

Error detected in WP:

object from empty value in /home/...../domains/...../public_html/wp-admin/includes/post.php on line 631

Any suggestions would be greatly appreciated because my hosting guy says this is beyond his scope and service.

Regards,
