Hello, Andres, thanks for answering.
I just copy the plain text from the original sites, it helps that they are blogs (Non-wordpress ones) so it’s as simple as copy-pasting. It has happened in the past than the “post” buttons were greyed out, but I never lost more than a paragraph when I reloaded the tab, and there weren’t any conflicts with plugins then either. I really don’t know why it never saved any of my changes past that first time when I just copied the text and set the title and some links. If at least it had warned me I could have gone through the hassle of copying every paragaph somewhere else, one by one.
