Solved.

So what I did:
1) Disabled the phpmailer code in wp-config.php (no errors).
2) Rename the WP-Mail plugin (no errors).

Thank you for you respons and I hope that others can solve this problem themselves. I did ask the Host (TransIP) to fix this issue as they are the ones who added the code in the first place. Not only in my wp-config.php but all of their customers. So I believe they should remove it everywhere.

Hello Gregor,
After posting this I did some research: seems that my host added some code after the “stop editing” line in wp-config:

/** HOST fix: sendmail does not support flags. This fix is needed in order to make mailing work. */
global $phpmailer;
if ((!is_object( $phpmailer ) || !is_a( $phpmailer, 'PHPMailer' )) &&
     file_exists(ABSPATH . '/wp-includes/class-phpmailer.php') &&
     file_exists(ABSPATH . '/wp-includes/class-smtp.php')) {
	require_once ABSPATH . '/wp-includes/class-phpmailer.php';
	require_once ABSPATH . '/wp-includes/class-smtp.php';
	$phpmailer = new PHPMailer( true );
}
$phpmailer->UseSendmailOptions = false;

I will set this through to them and let you know. However, that does leave the few lines:

Some error with PHPmailer I guess?

Hello Gregor,

This is literally what I get:

Didn’t receive the e-mail though…

That’s a fast one Jan!

To answer your questions one by one:
1. Where is WordPress installed on the file system? It looks like you may have in a subdirectory /winkel/ but the post redirects to the root.
1) it is in root/winkel.
2. Does /winkel/ exist as an actual subdirectory?
2) It actually exists as a subdirectory (created it myself).
3. When I visited https://www.superpersis.nl/winkel/wp-admin/ I was greeted with an interesting login prompt. Where's that coming from? If it is server based then there may be more going on here.
3) If you are referring to the WordPress attack protection; I was under the impression it came with WordPress? It is for sure server based. As WordPress was under attack quite often by hackers who used “Admin” and some random passwords to hack a site I could imagine that a registrar would like to rule out hacker software. It happened to me at my previous host btw, cost me quite some time…
4. What do you have in your WordPress SiteURL and WordPress Address? I think it's these two values
4) You are absolutely right about the two values.

So what does this tell us?

P.s. Winkel = Dutch for shop.

Hiya Jan,

Currently the .htaccess in the subfolder of jthosting.nl looks like this:

# Block the wp-config file.
<files wp-config.php>
order allow,deny
deny from all
</files>

# Block the include-only files.
RewriteEngine On
RewriteBase /
RewriteRule ^wp-admin/includes/ - [F,L]
RewriteRule !^wp-includes/ - [S=3]
RewriteRule ^wp-includes/[^/]+\.php$ - [F,L]
RewriteRule ^wp-includes/js/tinymce/langs/.+\.php - [F,L]
RewriteRule ^wp-includes/theme-compat/ - [F,L]

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

And in the root like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

The root .htaccess file of Superpersis.nl currently looks like this because of the standard option for permalinks: /?p=123 or something like that.

# BEGIN WordPress

# END WordPress

The subfolder .htaccess looks like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /winkel/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /winkel/index.php [L]
</IfModule>

# END WordPress

The Apache2 config file is on the same (shared) server and I could not find but I ask my registrar if ModRewrite is on and he confirmed this. Should I also ask him about the content of the config file?

Thank you for your reply Jan, I appreciate that!

Your reply made me reconsider my words after first being really annoyed that you said it didn’t happen with a clean install, which it did. I wanted to proof you wrong (read: proof me right) and installed WP 4.4 in a sub folder of one of my websites. After entering the DB information etc. the installation didn’t progress. So I checked with FileZilla to edit the config file. It was correct. I checked the original WP install and it was identical to the new install. It scared the sh*t out of me as I lost my website! So I restored a backup and all was well. That’s when it hit me: you were right! It’s not the regular install which shows this error, it’s an install in a sub folder.

There for I thank you for taking me/us a step closer to a solution. The problem still occurs though.

Why are pretty permalinks not working when WP is installed in a sub folder?

In the end I had to change everything by hand.

I’m disappointed that there’s no real reply to this thread and thus to the problem.

jthosting.nl

Don’t see why this would be helpfull though as you would just see the standard theme layout.

But if you have an answer, let me know! ??

Any idea on the progress for this issue?

Obviously it’s hidden on the website but check: https://www.jtgroep.nl/category/betaald. You should see the posts but are unable to view the content after selecting the post. I can relate to Ralph as I try to show posts via category to a specific user only. The post is restricted and so should the post shown by category.

Looking forward to the solution!
