20 (0x14) Execution of the module forbidden and the read access is not
Indicates that the ALP directory settings forbid the ALP module responsible
for the request to run and also the resource cannot be served as raw content
because the read access is also forbidden.
Check the ALP directory settings in the pointed directory. Sometimes this
error may be caused by the developer intentionally - to remind the users that
the application must be used in the manner for which it has been designed and
not by manually starting particular files from it.
