Ok, after finding out my old installtion of PHPvms did not work with php 5.5, i installed a new version using the simpilots group version. I am using my exisiting database for this installation
However, in the admin section, there is no option to manage my fleet in the airline operations section as per before?
I suggest you back up your whole website with all the data then wipe out everything and install a fresh copy of phpVMS then import your tables one by one. Remember to create an airline with the same code as your DB tables such as airlines, schedules.
