@ashleighm Could you please comment out this line and see if that fixes issue? https://plugins.trac.wordpress.org/browser/post-smtp/trunk/Postman/extra/no-localhost-mails.php#L8

If there are no other plugins, except WPO and Post SMTP, then probably post smtp wrongly conclude cached site as localhost and define wp_mail

Mere existence of wp_mail sets $this->bindError as true

As I said earlier, WP Optimize don’t declare function wp_mail which you can test by searching the source code. You are saying that no other plugins are there and theme as well doesn’t declare it. So above is the only possibility I see

@ashleighm It doesn’t have to be MailGun Any other plugin that deals with sending email such as mailin by sendinblue or CF7
See here https://wordpress.org/support/topic/wp_mail-declared-by-another-plugin-theme/

If you have enabled Log events to email in Logging settings in WPO, try removing it.

@laserstore Could you please provide Cache => Advanced Settings page screenshot to refer the settings in URLs to exclude from caching ? Thanks!

Also, do you see wpo-cache-status: cached header in your html response?
See how to check it here: https://stackoverflow.com/questions/4423061/how-can-i-view-http-headers-in-google-chrome

@ashleighm How do you conclude that it is WP Optimize that causes the issue? Yes, WP Optimize uses wp_mail but it is not declaring it.

See the screenshot: https://prnt.sc/3SEqUoq6cDQv

In my case, it is Mailgun plugin that declares wp_mail Disabling it solves the issue.

@jas2021 In our testing it works fine. So, we would like to work closely with you to sort out this particular issue.

What is the exact issue? Form is not getting submitted?

Does it happens when you turn off cache?

With cache tuned on, does this happens every time even after purging cache?

Please submit the below form, so we can communicate in private. Thanks

@johnniefolker Add the following to your theme’s functions.php file

add_action('after_setup_theme', 'ab123_remove_robots_txt_entry');
function ab123_remove_robots_txt_entry() {
	if (function_exists('WP_Optimize')) {	
		remove_filter('robots_txt', array(WP_Optimize(), 'robots_txt'), 99, 1);
	}
}

@comprastodo Do you happen to have define('WP_DEBUG', true); in your wp-config.php file? If so, could you please change it to false and it should fix the issue.

@marcosf .htaccess recreation is expected since the uploads folder has write permissions. But I’m guessing that the created .htaccess file also have read/write permission in file system but somehow Nginx restricts it.

So could you please make sure that file doesn’t have read/write access? And it should fix the file_get_contents warning (since the code is already there)

We can’t code based on server software, because $_SERVER['SERVER_SOFTWARE'] is not always set
