I was currently having issues with this error 

(  Error Number: 1054
Unknown column 'editable' in 'where clause'
SELECT * FROM `cf_list` WHERE `editable` = 1 ORDER BY `id` DESC
Filename: modules/cf_manager/models/Cf_manager_model.php
Line Number: 96 )

I fixed this with the video from
https://drive.google.com/file/d/120ELNKfLNTZ_1fA0fhWM4MA1QNwu87t_/view?usp=sharing

now when I go to create a new custom field I get the error (Input invalid) 

error from the /logs/LogViewer.php

Query error: Unknown column 'default_value' in 'field list' - Invalid query: INSERT INTO `cf_list` (`user_id`, `label`, `default_value`, `fields`, `created_at`, `updated_at`, `editable`) VALUES (10, 'user', '', '[{\"type\":\"input.phone\",\"label\":\"phone\",\"default\":\"\",\"required\":\"0\",\"order\":\"1\",\"step\":\"1\"}]', '2021-05-19 12:33:46', '2021-05-19 12:33:46', 1)

Also for some strange reason when I did an install of v2.5 and not an upgrade I had to create the folders 

uploads/images/
uploads/files/
uploads/_images/

before it allowed me to upload images for stores and catagores 

I really need this sorted so I can move forwards with my project 

Thanks

Also the youtube video link is not saving to the database the table video_url is in the database but the links are not saved when creating a store 

hello 

After updating the store folder the youtube videos are now being stored in the database all fixed

Thanks

Please release an update to fix this.

This happended again and again with my dashboard too
