ZF-7565: Notes of Zend_Config_Ini parameter "allowModifications" is misleading
allowModifications: Set to TRUE to allow subsequent modification of loaded file.
I thought wrongly that modifications affect to the file, by calling automatically Zend_Config_Ini_Writer methods. This is not true.
To be clearer, you should replace this sentence with something like the following "Set to TRUE to allow subsequent modification of loaded setting data."
