Messed up or blank page (WordPress)

Messed up or blank page in back-end

Error

The Smart Slider's pages are messed up, or blank.

Solution

You can probably make your website write out the error, if you write this code inside your wp-config.php file right under the <?php part:

error_reporting(E_ALL);
ini_set('display_errors', 1);
ini_set("log_errors", 1);
ini_set("error_log", dirname(__FILE__)."/php-error.log");

and take a look on your messed up website or a php-error.log file should also appear in the root folder of your site (  http://example.com/php-error.log ). If that doesn't write it out, usually the problem is caused by the  Optimize images option, because with big images that can become resource heavy, and the memory_limit is reached in these cases. If you would use smaller images, it would be fine, or contact your server host to increase your memory_limit. If the problem is different, you can also just try to deactivate your plugins one by one, maybe you will find the problem like that too.  

Blank page after installation

Error
  • After activating the Smart Slider's plugin, blank page in the back-end.
Solution

This can happen, when the installation wasn't successful, and some files are missing. You should go to your ftp, and reinstall the Smart Slider with the Upload through ftp method. If you do this with a proper ftp program, like Filezilla, then you can see if all the files really got through, because some servers block certain filenames, and you should contact them in case you can't upload some file somewhere, as you should have 100% control over your files and folders in your ftp.

Messed up or blank page in frontend

Error

The whole page is messed up where the slider is, or it's just blank. 

Solution

This can happen, if you have a php error or a server limitation reached. You can probably make your website write out the error, if you write this code inside your wp-config.php file right under the <?php part:

error_reporting(E_ALL);
ini_set('display_errors', 1);
ini_set("log_errors", 1);
ini_set("error_log", dirname(__FILE__)."/php-error.log");

and take a look on your messed up website or a php-error.log file should also appear in the root folder of your site ( http://example.com/php-error.log ). You should look for Fatal errors, and you will see, if comes from a plugin or the server. You can also just try to deactivate your plugins one by one, maybe you will find the problem like that too.

Blank page maybe just after a number of slides

Turn off the  Optimize option, if it's on, because if you are using it with too big images, this is a resource heavy process, and probably your server's memory_limit has been reached. If this helps, either use smaller images in the future, or ask your server host to increase the memory_limit value of your website.

Messed up backend using AMPPS

First, try to make your site write out the error, which you can do like this. That will give you the idea if you need to turn on some PHP extension, or increase some server setting.

Call to undefined function ctype_digit()

You should enable the ctype extension at AMPPS Application → PHP Tab → PHP Extension. Check ctype and Apply.
