Hi I already have submitted a ticket one hour ago but im seeing the european office is already closed for next 14 hours so i opened this topic perhaps i will be able to fix this issue soon. Using aMember integrated with invision power board software and after upgraded aMember (from 5.1.3) to latest version i realized the users registered to aMember are not able anymore to login into forum nomore. The upgrade process went great,didnt got any error message, also no error at Error/Debug Log. What else should i check ??
