Slick

You have to inlude the static template again.

You can do the job by SQL statements or manually.

SQL Statement

SELECT

Get all records with an included static template of Slick - responsive Carousel Slider (slick):

SELECT `uid`, `pid`, `title`, `include_static_file` 
FROM `sys_template` 
WHERE `include_static_file` LIKE '%EXT:slick%'

UPDATE

-- replace the base template
UPDATE `sys_template` 
SET `include_static_file` = REPLACE(`include_static_file`, 'EXT:slick/Configuration/TypoScript/7.6/', 'EXT:slick/Configuration/TypoScript/Default/')
WHERE `include_static_file` LIKE '%EXT:slick/Configuration/TypoScript/7.6/%';
UPDATE `sys_template` 
SET `include_static_file` = REPLACE(`include_static_file`, 'EXT:slick/Configuration/TypoScript/Base', 'EXT:slick/Configuration/TypoScript/Default/')
WHERE `include_static_file` LIKE '%EXT:slick/Configuration/TypoScript/Base%';
-- remove non needed include static templates
UPDATE `sys_template` 
SET `include_static_file` = REPLACE(`include_static_file`, 'EXT:slick/Configuration/TypoScript/Carousel', '')
WHERE `include_static_file` LIKE '%EXT:slick/Configuration/TypoScript/Carousel%';
UPDATE `sys_template` 
SET `include_static_file` = REPLACE(`include_static_file`, 'EXT:slick/Configuration/TypoScript/Item', '')
WHERE `include_static_file` LIKE '%EXT:slick/Configuration/TypoScript/Item%';
UPDATE `sys_template` 
SET `include_static_file` = REPLACE(`include_static_file`, 'EXT:slick/Configuration/TypoScript/RemoveLLATag', '')
WHERE `include_static_file` LIKE '%EXT:slick/Configuration/TypoScript/RemoveLLATag%';
-- clean up double comma (repeat it!)
UPDATE `sys_template` 
SET `include_static_file` = REPLACE(`include_static_file`, ',,', ',')
WHERE `include_static_file` LIKE '%,,%';

Manually

Look for Slick templates:

Include the static template again.
