Hi
Recommended PHP Configuration Limits
Created September 30, 2015 Author Alex – Support Team Category Server problem
First please check that you are using version php 5.3 >
Many issues that you may run into such as; white screen, demo content fails when importing, empty page and other similar issues are all related to low PHP configuration limits. You can check it by installing a simple plugin found here.
The solution is to increase the PHP limits.
You can do this on your own .
Find the php.ini file in your Server config files.
For WAMP, its in apache2/bin/apache2.2.22/bin/php.ini
Go to the line “max_execution_time=30” .
Change it to 360 or any other large value.
Or contact your web host and ask them to increase those limits to a minimum as follows
max_execution_time 360
memory_limit 128M
post_max_size 32M
upload_max_filesize 32M
