What did this happen?
There are so many reasons that can make this Error Occur. A few are:
1. Could not Update the database
2. Database communication failed
3. Irregular value in form leading to mysql injection
4. Poor Newtork communication.
1. Could not Update the database
This Error occurs in forms especially when completing profiles. When you try to submit a request to the database and
there was no changes in the previous form, this error will occur. Another factor that can make this error occur is when
there is a poor communication with the server scripts and the database thereby leading to a failure in handshake.
But the major cause of this error is when a user tries to submit the form that has already been recorded by the database.
2. Database communication failed
With the advent of the mysql transactions, there is bound to be failure in a series of processes running silmutaneously.
If we are to process 3 to 8 request (Multiple Transaction), a failure in one of the transactions may also lead to this error.
If the mail server is down during your registration, this error will definitely occur.
3. Irregular value in form leading to mysql injection
When some irregular values are been caught up mid-way during database communication, this error is also triggered.
some special characters like the (') or the (") in fields like name, email, email address amongst others should be avoided.
4. Poor Newtork communication.
When there is a poor network connection, this error is also triggered. This happens when the load of the request you are trying to make is
larger than what the server can handle at that particular moment thereby leaving the request mid-way.
What do i do?
When this error is encountered, if you are in a profile update form, then check if the form has not been submitted before
by rereshing and checking if our details have already been updated (Form Resubmission).
If you are in a registration form or any other place, try resubmitting the form maybe in a better network condition
.Please as you are resubmitting the form, check out for some of the special characters listed above.
But i the problem persist, then the only way to solve the issue is to meet the school administrator complaining
about this.
