I dont know what i've touched, i changed one value in global_conf.php but it didnt do what i wanted it to do so i changed it back exactly the same as it was before, now when i click post reply it adds the reply but all you see is a blank white screen you have to clikc back on yoru browser and refresh to see you post added what could have changed?

in the admin cp i also get this next to uploads now:

I have a feeling this is related, does anyone know what could be wrong? i may have accidently dleted a value maybe in conf_global? does anyone have like a list of the values needed in there. You help would be appreciated.

Quick Edit: have also noticed links with &view=getnewpost also go to a white page??

what was this value you changed?

I changed the admin_group and auth_group numbers around, but i switched them back again when i saw nothing happened.

sorry for double post. A mod can close this topic, i resolved it by going to acp -> help and support and white space checker, found there was white space in conf_global so deleted it and its all good.
