Community lots.

now im assuming this is in one of the starter towns and now a town you got from the exchange (offten those towns crash and dont work right) 

try going into -edit town- mode and click on the school lot. click on the button that sets the lot type and change it. 

if this doesnt work then bulldose the lot. Place a new lot size where it used to be and go to -Build/buy on the lot-

from there go to Build and click on commun ity objects. There you will find a few schools from different towns (depending on what EPs you have) place one on the lot and save it. make sure to set that lot type as well. you dont have to put any fancy stuff around it you can do that later once you know it works. 

So Basically you want to change 'No Visitors Allowed' to 'Visitors Allowed'. To do that you go to the Options menu, then into Edit Town mode, then click onto the school, then click 'change lot type', and then scroll through the menu and changed it to 'visitors allowed' then go back onto live move and your child Sims should be able to go to school.

Hope this helped 😕mileyhappy:

thank you for getting back in touch and helping 🙂 i can do all that apart from the edit part, where you go to place the new school there in the community part, there is no schools or anything, they've all disapeared :/ i have no idea how to get them back either.

Sorry if this is all confusing, i literally done nothing to the game, was playing it as normal then just yesterday the children didn't go to school so i wondered why i found this out. Thanks for your time 🙂
