I get weird behavior Magento 2.
I get a 500 error only on the home page, and on all other pages everything works correctly.
How can this be fixed? Please, help)
go to bootstrap.php which will be in app/bootstrap.php (nano app/bootstrap.php) and uncomment the #ini_set('display_errors', 1);line in the sense it will be like ini_set('display_errors', 1); it will help you to show error message in front-end and fix the error.Happy coding fell free to drop any comments
Try to remove the .htaccess file from your Magento root folder and then try to load your website in the browser.
If it doesn't give 500 internal server error after removing the .htaccess file, then there must be some PHP version issue or any server configuration is missing.
If using apache for example not having an additional module like mod version will throw 500 error. So you are not reaching magento application. Which means nothing in magento logs.
You will have to try and check server logs too. Exact location will be different depending on your stack.
I solved problem!
It all consisted in the fact that the header was very large, or rather its size is 9.5 kilobytes, and the nginx limit was 4 kilobytes
I increased the limit for nginx
The header itself is formed so large due to client settings: for products in the carousel, it was mandatory to display the product id in the carousel in INSPECT, which is displayed on the homepage using the widget
