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.
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
Successfully importing data into WordPress is not something we can guaranty for all users. There are a lot of variables that come into play, over which we have no control. For example, one of the main issues are bad shared hosting servers.
