[Resolved] Unable to publish a post since updating the extension this morning

Hello,

First of all, I would like to thank you for your extension, which is really great.

Since updating your extension this morning, I am completely unable to publish articles on my site, receiving the error message: “Publishing failed.”

I have investigated the issue as follows:

I deactivated all extensions and reactivated them one by one until the error appeared. Unfortunately, the error occurred with your extension.
I activated all the extensions on my site except yours: no problem.
I deactivated absolutely all the extensions on my site and left only your extension activated, and the problem occurs again.
I should mention that I am using WordPress version 6.7.

I would be grateful if you could assist me.

Thank you for your assistance.
