Hi,
thank you for advice!
I checked error message and find that one of plugin make this. I notice that when I’m going thrue ftp there is catalog “plugins-old” so I changed it for name plugins and catalog called “plugins” changed on name “plugins1” and see whats happen. Site start working but without any plugins so I noticed that catalog with plugins-old was empty. I changed catalogs for orginal (pervious names) and now there is still no plugins working.. Site is working now but wihout any plugins. Do you know what happend ?
