I have updated the WordPress to the lates version (3.4.2) and it has become a nightmare.
1) Very nice panel in "visual" (not html) which existed in previous versions version has gone and I can't find it
2) The text in visual versions cannot be seen. Thus, I can't edit anything - and it's a nightmare than you try to enter mediafile
3) All the comments in my site (pavelshkapenko.ru) have disappeared. Moreover, even than you try posting new ones they are still not shown on the site.
It's a real nightmare, so I would thank everyone who could be to solve any of these 3 problems.
