Hello,
At a Prestahop installation , PS v 1.7.5.1 , PHP 1.7.3.3 , Nginx 1.10 , friendly urls on with Greek and English Language i had errors
"An error occurred while processing your request prestashop"
The error was triggering for products with attributes , e.g sizes , when selecting a different size
The error fixed after adding at nginx.conf the following x
### [Friendly url MULTILANG]
### change el$, el with your language code , eg fr , un-comment and change language code for more languages
rewrite ^/en$ /en/ redirect;
rewrite ^/en/(.*) /$1;
rewrite ^/el$ /el/ redirect;
rewrite ^/el/(.*) /$1;
# rewrite ^/es$ /el/ redirect;
# rewrite ^/el/(.*) /$1;
(restart nginx)
The fix adapted from https://github.com/PrestaShop/PrestaShop/blob/develop/docs/server_config/nginx.conf.dist#L103
* The sample nginx.conf is available at downloaded prestashop.zip, folder \docs\server_config\nginx.conf.dist
The sample nginx.conf requires edit to mach your server settings
I hope it will help someone!
