Доброй ночи!
У меня помогло таким способом (стоит на локалхосте):
1) поменял настройки в C:\WebServers\usr\local\php5\php.ini
max_execution_time = 360
; Maximum amount of time each script may spend parsing request data. It's a good
; idea to limit this time on productions servers in order to eliminate unexpectedly
; long running scripts.
; Note: This directive is hardcoded to -1 for the CLI SAPI
; Default Value: -1 (Unlimited)
; Development Value: 360 (360 seconds)
; Production Value: 360 (360 seconds)
; http://php.net/max-input-time
max_input_time = 360
; Maximum input variable nesting level
; http://php.net/max-input-nesting-level
;max_input_nesting_level = 64
; How many GET/POST/COOKIE input variables may be accepted
; max_input_vars = 1000
; Maximum amount of memory a script may consume (512MB)
; http://php.net/memory-limit
memory_limit = 512M
2) перезагрузил Денвер
