How It Affects Your App
The error 1696 ER_FAILED_READ_FROM_PAR_FILE indicates that the application is unable to read the parameter file. This can cause the application to fail to start or to crash unexpectedly. It can also lead to data corruption or data loss, as the application may not be able to access the necessary data. In addition, the application may be unable to access certain features or functions, as the parameter file contains the necessary information for these features. As a result, the application may not be able to perform as expected.
