I have installed the SUPEE-8788 patch in Magento 22.214.171.124 CE. At the first time I have installed the v1 of the patch, now I have reverted it and I have installed the v2, but the issue persisting. When I try to change the image background in a slide of AM Revolution Slider, the "Browse File.." doesn't work, I can't change the image. I'd try to clear Magento cache, browser cache, restart Apache2 but nothing. I'd check the source of page and this file are not present:
Someone has an idea how I can solve?
