Sure.
I must have tried 20 plugins and scoured the internet looking for a solution to WordPress adding/or subtracting html code (eg , <p> or removing space in html so that code gets jumbled to close together) when switching from HTML edit view to Visual View and back. I think when I tried this plugin, I was at my wits end so I was short.
Anyway, I now use a plugin named “Preserved HTML editor markup” and it seems to do the trick…finally. One issue that still remains which I can deal with. I’m not 100% sure but I think if I have some unclosed P tags…then WP will still try to fix them (adding more P tags) even with either of the mentioned plugins installed.
Hope that helps.
