Hi there,
Where can I find the complete changelog for Akeeba Backup for WP - version 9.1.0?
Since the update I'm having problems with the akeebabackup API. So I was wondering if there are any changes in the API.
Thanks for the support.

Go to https://www.akeeba.com/download/backupwp/9-1-0.html and click on Show Release Notes.
That said, I have not touched the API. Can you please tell me what you are trying to do and what happens?

Hi Nicolas,
Thanks for the quick response.
I am using Akeeba Backup in conjunction with MySites.guru tools. This works perfectly but as I just updated Akeeba backup from v9.0.6 to v9.1.0. The connection breaks.
However Akeeba is still working perfectly in the WP-admin. No problems there.
I have been in contact with MySites to sort this out and the send me this:
The fatal error is:
<b>Fatal error<\/b>: Cannot redeclare class Composer\\Autoload\\ClassLoader (previously declared in ...ClassLoader.php:43) in <b>phar:.../httpdocs\/wp-content\/plugins\/akeebabackupwp\/app\/restore.php\/vendor\/composer\/ClassLoader.php<\/b> on line <b>43<\/b><br \/>
This is EITHER an Akeeba Backup issue, or an issue with one of your plugins/theme
We are just accessing the JSON API published by Akeeba Backup, none of the mySites.guru code runs at this point. Its a straight HTTP POST to the JSON API endpoint.
You should attempt disabling other plugins to see if you can find one that conflicts, and/or report this to Akeeba support.

Hope this makes sense to you.

Johan
Yes, it does. It comes from an obsolete JSON API method that should've been removed… um… in October 2023. It looks like the code to actually remove those files was never included Akeeba Backup for WordPress 8 or 9. Let me run an upgrade test now that I have enabled it and I will make a new release.
For what it's worth, I have confirmed that removing the obsolete JSON API methods manually does fix the problem on a real site, so I am positive that I am on the right track here.

Many thanks Nicholas.
Please take your time. There is no rush on my end as I do have a fall back to the wp-admin.

It was a silly mistake on my part. I made the fixed release a few minutes ago.
