Hello everyone here. I do need your help. Im new in these area and the question is: After the EasyApache 4 reset and provision, is it must the Script Installing again, like ffmpeg, mp4box, yamdi, x264, imagemagick and youtube-dl etc. Because few days before in WHM/ EasyApache 4 Im try to set something that want the server run perfect, but I made a mistake that change the DSO to CGI, so all the site is fail, and then I change back, the site start run again, but I think still something error there, as at the site Admin area, the FFMPEG, YOUTUBE-DL .etc are not working. I do remember before in WHM somewhere I can see the ffmpeg, mp4box, yamdi...there.but I forgot. Thanks for your help and have nice day Jun
