A huge thank you. I had already googled, but I hadn’t found this page. The link you shared contains the problem solution! V3 Database Migration Fails | www.ads-software.com

It can be revised and republished without errors and the re-release also works. THANK YOU

Ah I just read in the one link that it may actually be that the plugin “leaves” something. I will try the solution mentioned there and get back to you. Thank you

Thank you for the quick reply and your help. I haven’t used the Link Whisperer plugin for at least over a year. And after discontinuing the plugin, there have been no problems with Yoast Duplicate Post plugin so far.

Do you think a plugin that no longer exists can cause this error? Then I like to ask the support, but since the error is new and the plugin has not been on the site for a long time, I would be a bit surprised.

I’m relatively sure that the Calender plugin is not the problem. Fortunately, I was only able to use this plugin on the originally planned (revised) articles. Otherwise, all the revision would have been lost, as the article could no longer be found in the backend.

Please excuse the late feedback, I first had to find someone to help me read the error log.

Thank you. Sorry, I was on vacation for a week. Yes, that is the correct calendar plugin.

I can’t find any server error logs, but I have emailed the hosting provider.

I have deactivated all my plugins, and the error persists. It seems that the issue lies with Yoast Duplicate Post. I will get back to you with the response from the hosting provider.

Hi Mushrit, thanks a lot. I will have a look, where I can find the server error logs.

The Calender Plugin is: WordPress Editorial Calendar

I will check for the errors first and get back to you. I think it will be difficult to reproduce if you don’t have the error.
