In addition, it also corrupts database by adding duplicate quotes.
Hello, I apologize for your displeasure, so I hope I can help you.
The current version of the plugin is 4.0.6 and, as far as I know, I have tested it with old installations and the update has worked correctly.
As I have added functions to the plugin, the database tables have been expanded, and even existing ones have been modified.
Tell me where you are and from which version you have updated so I can replicate the error and provide you with a solution.
Regarding the fact that it is in Spanish, it is true that it includes the .mo and .po files in Spanish, but if the language of your site is different from es_ES all text entries will be displayed in English. All files are ready to translate the plugin using Poedit.
I await your comments, and I apologize again, but there have been significant medical issues that have kept me away these years; now I hope to be quicker in my responses.
Thank you for your comments.
