By upgrading to 1.822 you remove a possible security risk in a module.

This risk can only be exploited if you have admin permissions.

You should checkout how to upgrade

Besides from this you should edit config/config.ini

You need to find the following lines describing the blocks enabled:

blocks_top[0] = "/modules/system/blocks/system_admin_menu_top.inc"
blocks[1] = "/modules/content/blocks/content_tree_keep_state.inc"

And remove the /modules part:

blocks_top[0] = "system/blocks/system_admin_menu_top.inc"
blocks[1] = "content/blocks/content_tree_keep_state.inc"
