Issue using plugin with Nginx/Php-FPM but works with Apache/PHP

I'm using a Wordpress plugin called Ultimate Addons (https://codecanyon.net/item/ultimate-ad ... er/6892199). One of the pages within the plugin allows for uploads of icon files (.zip files). When using Nginx and PHP-FPM, the upload process just hangs. When using Apache and PHP, it's successful. I don't have any errors in php-fpm logs, nginx logs, or with WP_DEBUG. The upload process is dependent on a module ZipArchieve, which I can confirm is installed and working since it's required for another plugin which works fine and I've even got a web config page which reports it's installed and working.

I'm also very certain the issue is not permissions related. All files in my public_html dir are chown'ed to admin:admin (since I'm only using this one default user). I've also set all folder and file permissions to 775 and 664 respectively. I have SELinux turned off.

Operating system is Centos 7.

I'm not sure where else to go with this issue. Any help would be great.

btw, just for fun and for testing, I upgraded to PHP7 to see if the results would be different, but nope.

Without any errors we really can't help you.

When starting this again try opening Web Developer tool and see if the console reports a Javascript error.

Shouldn't have any effect on nginx / apache but it's worth a shot.

It's either a) it's using .htaccess somewhere and obviously nginx does not use this or b) the module is not installed for nginx.

If it's a) no errors other than "not found" would be produced.

Ok I have a POST error, but I can't really interpret it well. I enabled debug logging for php-fpm but still don't see anything in the error log. Again there's nothing in Nginx error.log either for this site. Here's a copy paste from the console error in Google Chrome:

It's a 500 error so it should be producing errors in the error log for that domain in nginx/apache. 500 errors are always reported in the error logs.

you're absolutely right! And with an nginx restart, it started logging again. Here's the capture.

Looks like there's a problem with the plugin?
PHP Warning: simplexml_load_string(): Entity: line 11: parser error : Entity 'raquo' not defined in
raquo is a HTML entity.

http://stackoverflow.com/a/6208803

Obviously not wise to directly edit a plugin but the answer is on Stack.

It may be that nginx is not processing an .xml file as xml (mime types)? Hard to tell basically.
