I have a problem with position plugin, as i can create new positions, but cannot change any functions in the row settings. Mabye you can advice something. As when i made that website (in 2015 ) it wasn’t a problem. I changed the server to php 5.6 since that, but now i should add some information, but i cannot.
Thanks for your info.
