installer file download fails

now on two totaly different hoster the same – first i thought that this special install has the problems – but now now two more installations show this behavior and creates bak files. By the way the ftp transfer does not work anymore. Something that does work all the time. I can login via ftp Client with the settings. But Transfer via duplicator not.

maybe the download fails on that first server because United Domains have not activated the mod_headers on apache? that is the only difference – but even on the other Hosters – a migration leads to a supposedly successful action – but wp-login page ( with the new domain ) leads to the admin area of the origin WordPress installation. ??

Free Version?: 1.5.5.1

Same problem on clean install.
I use old PATH, all other parameters to default; the files created are named :

Packet_123456798_123456789_archive.daf
Packet_123456798_123456789_installer.php.bak
Packet_123456798_123456789.log

If I rename manually …_installer.php.bak to …_installer.php, all work fine to restore

Looking forward to hearing back from you.

Try doing the below points, Let’s break down your concerns and potential solutions:

Installer File Download Fails and Becomes installer.php.bak:
This issue might be related to server configurations, file permissions, or the way the installer script is handling downloads. Ensure that your server supports PHP 8.1 and check for any server-specific restrictions on file downloads. Additionally, make sure that file permissions are set correctly for the installer.php file.

FTP Transfer Issue with Duplicator:
If FTP transfer worked previously but now it’s failing, there could be several reasons, such as firewall settings, FTP server issues, or changes in your hosting environment. Double-check your FTP credentials, ensure that your firewall or security settings aren’t blocking the connection, and consider contacting your hosting provider for assistance.

Mod_headers and Apache:
If mod_headers isn’t enabled on your server, it might affect some functionalities, but it shouldn’t directly lead to the issues you described. However, it’s a good practice to enable it if your server allows, as it can be useful for various web applications.

Migration Leading to Wrong WordPress Admin Area:
This issue might be related to incorrect database settings during migration. Make sure that when you migrate, you update the WordPress site URL and home URL in your WordPress database to match the new domain. You can do this in the wp_options table of your database. Also, ensure that any caching plugins or server-side caches are cleared after migration.

Multiple Hosts with Similar Issues:
If you’re experiencing similar issues on different hosting providers, it’s worth considering whether the issue lies with the WordPress installation itself or the migration process. Verify that you are using the correct migration process for your specific setup.

Check for Errors:
Look for error messages in your server logs, WordPress logs, or browser console that might provide more specific information about what’s going wrong during these processes.

Thanks @zeeshan31

Many thanks for the tips and advice. Based on the hints from the health section that wordpress has been offering for some time, I wanted to test a persistent object cache plugin (SQLite Object Cache). This was probably the main reason for the inconsistencies. With the other domain, there was probably also the fact that different collations probably caused confusion.

With United Domains I had to set the headers via php. I actually only need this to define the content headers including the content security policies. Which I usually do via htaccess and mod_headers. Unfortunately, it didn’t work there. – My fear was that Duplicator might also need mod_headers.

I’ve made and downloaded a few backups over the last 24 hours. For whatever reason today I’m able to make a backup and download the install file fine but, the archive daf or zip does not download.

I just get the ” Site wasn’t available” error in my downloads in Chrome.

Duplicator Pro version 4.5.13.1
This and most of my sites are running PHP 8.2
