Hi Pavel,
unfortunately, your answer is not sufficient to me.
If you read 7549, you will come across 6310.
I think Marek N just gave up at last...
I solved my problem temporarily by changing index.php of my template.
It is a template that I !!copied!! under HU1.1.2 and never changed.
Already there is the discrepancy that the program code (index.php) does not match the HTML output. (add_css -> put_css_js sequence)
By the way, in "comingsoon.php" there are "extra lines", here "custom.css" is explicitly "written" again...
Even if I have solved my "problem" first, a funny feeling remains.
At some point I will have to ask myself again, what I have to adjust at the next update....
Sorry, but until "world's #1" it still needs a little bit.
