I’ve seen a similar error message on a few of my accounts, but I have not experienced the issues you have after seeing it. Most times the error appears, it seems to be for no reason, as changes are applied.

Are you still able to see your changes after the error? If so, this may be just a bug in the system.

Additionally, have you tried making changes through the AdWords Editor or another bid management program and uploading from there? I do a lot of my changes this way, avoiding problems like the one you’ve described.

“There was an error with your operation. If you were trying to make a change, it may not have saved. Please refresh this page to try again. If the error continues, log out of your AdWords account, then log in again and return to this page.”

I have tried everything…logging out and logging back in, turning off my computer, I’ve tried multiple browsers (Firefox v3.5.2 and Safari). I have downloaded the latest updates for my computer (Mac OS X 10.5.8). I’ve seen this question once already on the Google Help forum but no valid responses. I’m clueless…

I myself and still working through the finer points of the new interface. The pleasant thing is I’m not having troubles like I thought I would with the change. It’s actually been quite an easy transition.

I hope your experience with it turns out as well.

Go to ‘All Online Campaigns’ in your account. You should see all of your campaigns listed in the Campaigns tab. Now click on the Settings tab, and the list of campaigns remains, but you now see the settings you are able to apply to all campaigns. These are Status, Location, Language, Networks & Devices, Bid Type, Budget, End Date, and Ad Scheduling.

Let’s assume you want to bulk edit all of your campaigns.

First, click on the top campaign, and you are taken to the Settings page. Make the edits you wish to any of the above categories. Once finished, click on the ‘All Online Campaigns’ link at the top of this page, and you should be returned to the previous Settings tab list.

Now, check on the box to the left of the title ‘Campaign’ above your campaign names to select all campaigns listed. Now click on Edit beside the ‘New Campaign’ button.

You should now be see the ‘Copy To All Rows’ button beside any of the settings listed, allowing you to apply this to all of your campaigns.

If you only want to apply a setting to 7 of 10 campaigns, then instead of check the ‘check all’ box, check the 7 you wish to work with and when you press Edit, only these 7 will show the Copy To All Rows button and/or be edited when using this button.

I hope this helps. I know it’s not the greatest way to bulk edit, but it shows that it can be done, if only in a limited way.
