Solution for Jooma: "Error loading component: com_tags, Component not found"

"Error loading component: com_tags, Component not found" came after I updated manually Joomla.

To solve the issue check these steps:

1. Ensure folder /administrator/components/com_tags exists on the server. I have 5 folders and 5 files there.

If you have not this folder, upload it from joomla installation.

2. Check table *_extensions (v1_extensions) for element with name "mod_tags".

If you have not, execute this code (you could change the table name xvm7w_extensions on your _extensions table and extension_id on the first unassigned value):

INSERT INTO `xvm7w_extensions` (`extension_id`, `name`, `type`, `element`, `folder`, `client_id`, `enabled`, `access`, `protected`, `manifest_cache`, `params`, `custom_data`, `system_data`, `checked_out`, `checked_out_time`, `ordering`, `state`) VALUES (29, 'com_tags', 'component', 'com_tags', '', 1, 1, 1, 1, '{"legacy":false,"name":"com_
