Hello
Perfect! Sorry for not being able to reply earlier. I have updated the plugin to this new version and after several tests the error has no longer occurred. Really thank you very much!
The conditions in which the error appeared were a bit peculiar: I selected several entries, hit bulk edit and reassigned several categories and put them in draft mode, all at once. Before the error came out and after the update it works fine.
Again I reiterate my thanks for the time, interest, speed and effectiveness.
Best regards
Carlos
