Thanks for the quick response!

Not sure that is the case here. All plugins are installed using the wordpress dashboard. The only time I use FTP is when I need to remove the updraftplus folder after a failed update.

Also this is the only plugin that is causing issues for me. So it is a bit strange, I can’t think of an issue that could cause this.

Changed topic to unresolved again.

I’m not sure what is going on with the update progress but after every single update of UpdraftPlus I have the same problem.
Currently my update process looks like this:
Update UpdraftPlus fails -> I remove the updraftplus folder using ftp -> Install UpdraftPlus again.

This problem only happens with UpdraftPlus, the update process of other plugins works without any problems.

Does someone have a idea what is causing this?

Thank you problem solved and all settings intact.

Thank you for the help.

Just for future reference and additional information for users with a similar problem. I contacted whos.amung.us and got this reply:

Simpli.fi is not malware, it is a data categorization service used via one of our partners that we will be using to provide more insight into our users audiences via new stats we are going to provide.

You can of course prevent any third party services from being used via our services by adding the following javascript before the widget code:
<script type=”text/javascript> var _wau_opt = {‘fbase’: 1}; </script>
This will limit some aspects of our stats pages (what is being copied) however everything else will run as expected still.

Hope this helps.

So simpli.fi itself is safe, although it gathers some data.

Finally simpli.fi is present in a number of malware infected sites that add ads, I assume those harmful scripts only use simpli.fi to make their ads better target the audience.

Now it is for yourself to decide whether or not you want to get rid of the simpli.fi script.

I finally found it. A widget to show visitor information from https://whos.amung.us was adding the script.

At the bottom of my page, see screenshot below:

Also you can find my blog at bots.uthar.nl if that may help in finding this problem.

Thanks for your help so far James. But the plugins and theme were the first two things I tried (as stated in my first post.)

Another thing I tried was downloading all my data from the website and searching through all the files for the text “simpli.fi” using notepad++. But that also gave no results.

That one looks fine:

<?php
/**
 * Front to the WordPress application. This file doesn't do anything, but loads
 * wp-blog-header.php which does and tells WordPress to load the theme.
 *
 * @package WordPress
 */

/**
 * Tells WordPress to load the WordPress theme and output it.
 *
 * @var bool
 */
define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp-blog-header.php' );

So far all files seems to be clean and the following security plugins are not able to find anything:

Sucuri Security – Auditing, Malware Scanner and Hardening
Quttera Web Malware Scanner
Asgard Security Scanner

No idea where that script is coming from.

Sounds like a good solution.

@plugin Author
Will this be implemented in the next version?

I’m now using the plugin “Easy WP SMTP”:
https://www.ads-software.com/plugins/easy-wp-smtp/

With that plugin it works again but I have no idea why my emails stopped working. It was working fine without any plugin for years.

The PHP mail() function is not blocked and should be working fine. No idea though why I’m getting this error then ??

I found a similar topic at:
https://wordpress.stackexchange.com/questions/95016/wordpress-refuses-to-send-mail-your-host-may-have-disabled-the-mail-funct

I should have some time this weekend to try those steps.

Yes, I know. But I don’t have access to the configuration. That’s why I said I’ll contact my hosting provider again.

When I know more I’ll let you know. Thanks so far.

I just tried using: wp-login.php?action=lostpassword to try the email function.
It gave me an error that it failed to send the email because the PHP mail() function was probably disabled.

Very strange :/ When I contacted my hosting provider they said everything was fine. I guess I’ll contact them again.
