404 error - when trying to access modules/products in back office

[IDragos]

Greetings,

I am having some problems. The hosting company just switched from Apache to another type of server:nginx/1.12.2.

I am unable to access modules and products. I can not add new products, modify existing ones. 

The theme is Warehous 1.7.1.

Please help if you know the solution or you have been in the same situation.

Can you disable non prestashop modules and overrides? Try to do it first.

404 is a redirection problem on your server. You should contact your provider. If they changed frro Apache to nginx. so the rewrite rules should be adpated as well.

Perhaps you need to adapt Prestashop's .htaccess by your own. Normally when nginx proxied is used, there is no need to make any change. If nginx is used so the .conf-files should be adapted.

See docu here in the mid you will find nginx specifi rules: http://doc.prestashop.com/display/PS16/System+Administrator+Guide

For more details on adapting your .htaccess if provider cannot help you will find over the net: https://www.google.com/search?q=prestashop+nginx+.htaccess&ie=utf-8&oe=utf-8&client=firefox-b-ab
