Hi Nicholas,

Nice new site!

I've justed upgraded to ABPro 3.5.0, and now I get a 500 error when trying to access Extension manager.

Thanks,

If you are receiving a blank page or a fatal error when trying to access Akeeba Backup and/or receive an AJAX error during backup right after upgrading to Akeeba Backup 3.5.x, please note that this is the result of a partial upgrade. This is the same thing in your case: the System Restore Points plugin tells Joomla! to actually load a special view of Akeeba Backup when you try accessing Joomla!'s "Manage Extensions" page. There is a known bug in the Joomla! extensions installer (which is also used by our Live Update to perform the actual update). When upgrading to a version which has a different count of top-level directories, Joomla!'s extension installer "forgets" to copy all files and folders or remove the old ones. This usually happens when upgrading from Core to Professional and when upgrading between minor releases, e.g. 3.4 to 3.5.

The solution is very simple. First DO NOT UNINSTALL Akeeba Backup and DO NOT DOWNGRADE to an earlier release. The former will remove your backups and settings. The latter will cause Akeeba Backup to fail. Instead, go to our Downloads page and download the latest installation package of Akeeba Backup. Go to your site's back-end. Go to Extensions, Manage Extensions and make sure that the "System - System Restore Points"(*) plugin is either not installed or, if installed, is not published. Then go to Extensions, Manage Extensions and use the Browse button to locate the installation package you downloaded. Then click on "Upload and Install". You may have to repeat the installation a second time.

(*) The name of the plugin may be localised if your back-end language is other than English. In this case use the filter drop-down called "- Select type -" to "system" and look for the entry where the Element column reads "srp".

Hi Nicholas,

Thanks for that.

Unfortunately I get an 500 error when I try to open Extensions> Extensions Manager

So I can follow your instructions!

I look forward to hearing from you.

Thanks,

Bass

Ah! You meant disable the System Restore Point in Extensions> Plug-in Manager.

I did that, and Extension Manager returned.

I've re-installed ABPro from Extension Manager, but I still get the 500 error when I go to Componets> Akeeba Backup.

Have reverted 3.4.3, which seems to be fine.

Any thoughts?

Bass

Mmm! Actually 343 is not working. I've re-installed 350, successfully, but I get:

AJAX Loading Error
HTTP Status: 0 (error)
Internal status: error
XHR ReadyState: 0
Raw server response:

Let's try it again.

1. Start by removing the following folders:
- administrator/components/com_akeeba EXCEPT the administrator/components/com_akeeba/backup directory and the administrator/components/com_akeeba/akeeba/serverkey.php file. If you remove that directory and that file you will lose your existing backups and/or settings.
- components/com_akeeba
- administrator/modules/mod_akadmin
- media/com_akeeba
- plugins/system/plg_srp
- plugins/system/plg_akeebaupdatecheck
- plugins/system/plg_aklazy
- plugins/system/plg_oneclickaction

2. Download the latest installation package of Akeeba Backup.

3. Go to Extensions, Manage Extensions and make sure that the "System - System Restore Points"(*) plugin is either not installed or, if installed, is not published.

4. Go to Extensions, Manage Extensions and use the Browse button to locate the installation package you downloaded. Then click on "Upload and Install".

5. Repeat step 4 (and only step 4) a second time

All sorted. Many thanks, Nicholas.

Hope the conference was good.

You might like to know that I only got an email notification of your first response, and only saw your second response by chance.

cheers,

You're welcome, Bass!

Both emails were sent out. Are you sure my second reply didn't end up in the spam folder?
