Maybe try that :
That’t really was JUpgrade issue. In #_categories table element with id=1 was a category from com_webliks, and some categories had level field with value of 0. I was really surprised, because com_jupgrade is the solution in Joomla’ official migrate documentation… With next queries I fixed some problems, but others problems I had to fix manually.
UPDATE `#__categories` SET `level` = ‘1’ WHERE `#__categories`.`level` = ‘0’;
INSERT INTO `gostev_gur`.`j25_categories` (`id` ,`asset_id` ,`parent_id` ,`lft` ,`rgt` ,`level` ,`path` ,`extension` ,`title` ,`alias` ,`note` ,`description` ,`published` ,`checked_out` ,`checked_out_time` ,`access` ,`params` ,`metadesc` ,`metakey` ,`metadata` ,`created_user_id` ,`created_time` ,`modified_user_id` ,`modified_time` ,`hits` ,`language`)VALUES (‘1’, ‘0’, ‘0’, ‘0’, ’13’, ‘0’, ”, ‘system’, ‘ROOT’, ‘root’, ”, ”, ‘1’, ‘0’, ‘0000-00-00 00:00:00’, ‘1’, ‘{}’, ”, ”, ”, ‘0’, ‘2009-10-18 16:07:09’, ‘0’, ‘0000-00-00 00:00:00’, ‘0’, ‘*’);
Thank You!
