After enable merge Js in M2 Backend: Store/Configuration/Advanced/Developer and save the config, I can’t click any menu buttons in the backend. I think that Js is broken and I can’t go to Merge Js config and disable it again. Does anyone know how to solve this problem?
You go to database of Magento 2 site, run this SQL command:
SELECT * FROM
path LIKE '%dev%'
Change ‘dev/js/merge_files’ to '0’
Then run deploy theme command with SSH to see if it works?
