Undefined index: wp_db_temp_dir

Same problem here!
I can’t find a way to get rid of this error..

I have the same problem ?? pls help

..the only ploy at the moment is keeping deactivated the wp_db backup plugin, activating it only when I need to make a backup..

Yep, same here

I made a pull request that fixes this: https://github.com/matzko/wp-db-backup/pull/27

Same here. I will have to deactivate and activate when making a backup as suggested above

I’m getting this same error on 1 out of 4 websites using this plugin (all on the same hosting). Any fix yet?

You’ll only get this Notice if Debug is set to on, which it shouldn’t be on a live site.

Yes, but still a bug, very easy to fix and the only plugin in our environment which floods the debug logs…

Same here, majority of my webistes give this error. It would be very nice if this could be fixed!

Author doesn’t seem to want to fix the problem. I commented out line 112 and the error goes away as per other posts.

Changed this:

$requested_temp_dir = sanitize_text_field($_GET[‘wp_db_temp_dir’]);

to this:

// $requested_temp_dir = sanitize_text_field($_GET[‘wp_db_temp_dir’]);

Hi Gibsongk55,

Thanks for your reply.
The fix didn’t work for me.

But today I realised that the problem is not in the code, but the fact that the database-backup can’t be send.
The database can be downloaded to my local computer, but can’t be e-mailed.
The accounts with the SMTP plugin installed have no problem.
