It turns out that if long did not run into problems can (few) forget what the solution. This morning I was troubleshooting a problem uploading images in WordPress, instead of success but appeared HTTP Error. The problem is that the solution on the internet averages the Apache assumption, which I use is Nginx.
So the solution is easy once we increase the maximum size limit that can be uploaded to Nginx:
I model a ride so 20MB.
After that restart Nginx:
service nginx restart
If still problematic means the cause exists in PHP-FPM. We first modify its configuration:
And edit the two settings below:
upload_max_filesize = 20M
post_max_size = 20M
So we increase the file size limit to 20MB.
Same with Nginx earlier, do not forget to restart PHP-FPM:
service php-fpm restart
