[Ecigg.no]

Hello! Really enjoying Prestashop, but cant seem to figure out how to fix this problem! When im backoffice, and try changing ordering type, and hit "save" button, I only get a blank page. Any solutions?

 

Please be clear, i need to be explained like a child xD

Hi and welcome to the PrestaShop community forum.

 

When blank page, enable PrestaShop debug mode, then you can search on parts of this error message to hopefully find solution.

 

Here is how:

Hello. Does it look like i need to reinstall prestashop? Really need help with this

I have exactly the same problem after reinstalling prestashop.

Seems that htaccess is not in the root directory and its not possible to regenerate because the fatal error / server error 500 shows when saving after changing to frently url. (Known way to regenerate HTACCESS)

 

I cant solve the problem - have tried to reinstall

You do not need to downgrade to php5.2 or php5.6. PHP7 is the next level and your Prestashop website will run very fast. Just change Validate::$values['property'] to Validate::{$values['property']}.

I wrote an article about Prestashop with PHP7 here : https://www.prestasoo.com/blog/fix-error-when-save-preferences-on-prestashop-with-php7.html
