Hello,
Since installation of patchs, i can't upload pictures on product page in back-office.
When i try to upload i have this error in my navigator console :
Uncaught SyntaxError: Unexpected token < in JSON at position 0
at JSON.parse (<anonymous>)
at String.parseJSON [as evalJSON] (browser.js:101)
at klass.onFileSuccess (browser.js:2186)
at d.<anonymous> (browser.js:54)
at d.<anonymous> (browser.js:2152)
at k (browser.js:2152)

at e.chunkEvent (browser.js:2152)
at f.event (browser.js:2152)
at XMLHttpRequest.doneHandler (browser.js:2152)I have no error in my magento log exception, or error.log of my server.
Someone already have this problem and can share his solution please ?
Sorry for my english,
Have a good day
