Hello,
Thank you for answering this big problem for me, new to wordpress.org (well understood)
The site is managed by me alone, difficult to understand everything about the documents mentioned.
I could just set up the ITheme Brute Force.
It looks like the hacking is blocked, but I receive almost every hour a notification again.
For about 10 days, alterations, blockages.
How to do it concretely to stop this.
Sucuri and Wordfence are as long to understand.
Thank you for your important help for me and our French association. http://www.alacartearts.fr
Best regards.
