I am having an issue with image upload on backend after apply patch 8788.
I have seen problems with upload image but this I believe is different as upload file doesnt trigger any action or display any error.
Basically buttons 'upload file' and 'remove' dont work, not firing any function, just do nothing.
I can browse file and select a file and open. After that I can see the image ready to upload.
But as I said upload and remove buttons do not respond.
I cant see any issue on server or php issue, only issue I see is js on console:
Things I have tried:
-Cache is cleared, even minifycache.
-all permissions on js and media. group is also apache group.
-Checked that modifications are made, patch was applied successfully.
-js files are present (instance.js, browser.js, flow.min.js, fusty-flow.js, fusty-flow-factory.js...)
Any help will be appreciated.
