Elasticsearch: product page “404 Not Found” and category error

[pessoal2004]

We are a stuck with elasticsearch, because we have two errors:

1) The search page work fine but after that if we select on product to open there product page we get “404 Not Found”. 

2) With elastsearch when we click at any category we get the error:
Warning: file_put_contents(/usr/share/nginx/html/log/20190219_exception.log): failed to open stream: Permission denied in /usr/share/nginx/html/classes/log/FileLogger.php on line 93

Any ideas to solve this will be appreciate.

When some error occurs, thirtybees tries to log it into file. But in your case, because of incorrect directory permission, it's not able to create file in /usr/share/nginx/html/log/ directory, thus failing with this warning. And we don't know the root cause of this problem, because the original error is lost.

So, first of all, fix the directory permissions so it's writable. Then test again, and let us know what error message appears in the error log.

Thank you datakick, you are right, my first issue was a permission question, now it’s solved.
My second issue still is not solved, the search page work fine but after that if we select on product to open there product page we get that page http://192.168.1.1/coffee-and-tea/Coffee/coffee-beans with  “500 Internal Server Error”.
Any help will be appreciate
