Hi,
> May I ask for explanation how empting logs like apache, php, mysql affects the wampserver initiation process?
Wampserver, by default, has an automatic cleaning option for log files whose parameters can be seen in Right-click -> Wamp settings -> Automatic cleaning.
These settings are given in number of lines.
The verification of the number of lines and the possible cleaning is done each time Wampserver is started.
It can happen, if Wampserver is not restarted often, that the number of lines increases considerably.
The only way to count the number of lines in a file is the PHP file() function which reads the file and returns the result in an array and then counts the number of elements in the array.
With a file with a large number of lines, it can happen that the execution of this function needs more memory than the limit assigned by memory_limit and therefore generates a fatal error before the end of the script, so the wampmanager.ini file is not updated.
Update 3.2.2 partially fixes this problem but cannot remove it if it already exists.
