Hello,
i can’t check everything you ask.
1-also the back end in unacessible exactly like the front end, then i can’t deactivate the other plugins
2-i checked by FTP the plugin and it isn’t hte last version.
i tryed some other things
1-updated the plugin by FTP, the result was a blank page for the back end and the front end
2-i removed the plugin by FTP, the result was a blank page for the back end and the front end
3- i installed a old backup in local and it have the same problem. (this backup work fine until some months a go, it was the same i used to transfer the site from local to online)
4- to be moe clear the problem is recent, everyting work fine more less one mont a go.
