I enabled the extension=php5_notes.dll in php.ini file and shutting down Apache 2.4.1.8 32 bits, running on Windows 7 32 bits, and PHP 7.0.1.
This dll file is stored in c:\xampp\php\ext.
After reload the server, an error appeared, like:
17:27:20 [Apache] This may be due to a blocked port, missing dependencies,
17:27:20 [Apache] improper privileges, a crash, or a shutdown by another method.
17:27:20 [Apache] Press the Logs button to view error logs and check
17:27:20 [Apache] the Windows Event Viewer for more clues
17:27:20 [Apache] If you need more help, copy and post this
17:27:20 [Apache] entire log window on the forums
I think that php5_notes.dll conflicts with this new Apache version.
