when I install the deom it get error

Hello shihivan,

Please ensure that you have deactivated wp debug from wp-config.php core file like this -> http://screencast.com/t/iWr0W63LguQj and for more information about wp-config you should find in this documentation here -> https://codex.wordpress.org/Debugging_in_WordPress Please make sure that you have set them all the permissions for upload folder in your Cpanel/FTP.

Also, this kind of problem could come from your system status parameters and you have to increase these values in order to achieve the best result. If you do not have access to your system status file, please contact your hosting provider and then try to increase these parameters.

Please make sure your system status parameters are set properly. You can check here: http://screencast.com/t/Ka9cF6ty and then you can use this guide to see how you can increase these values: https://forum.tagdiv.com/system-status-parameters-guide/

Hope this helps and let us know how it goes!

Thank you for the message!
