Hello, Greetings! of the day. I have checked perl error message, which is displayed, when login button is clicked on staff login page at URL, provided in project description. According to that error message, there is some error in reading file, using perl login script. Is there any perl upgrade, done on server? To resolve this issue, the perl script code will need to be debugged.
I have much experience in working on projects, using required skills. Your work will be done, at the earliest, according to requirements.
