Thank you so much for your note. I’d never thought the problem may be in the WP editor itself. Thanks to your remark, it took just a minute to google and correct it (disable plugins affecting the editor, switching to a WP native theme, clear cookies, switching back to Preferential).
I’ll take sometime to check the code of all posts as there are some old residues. Using just your fonts enlarge with html % code. I’ll then see how it looks like. And maybe there will be a tutorial about some font customization by that time 😉
ok, new thread for each topic. Understood.
UPDATE: the problem with p / br tags and other formatting in WP editor were caused by Preserved HTML Editor Markup plugin.
