I´ve read this post, that has an accepted solution, wich didn´t solved my problem, so, that´s why I´m opening a new issue, because I think they are related, but certainly not the same.
I´ve have a Drupal 7 installation.
I have an Omega Subtheme.
I´ve set “Rebuild theme registry on every page” ON.
When I try to enable css compression, the themes are gone.
Not only my own subtheme is gone, but the administration theme is gone too (it´s the “seven” core theme).
To solve this I´ve tried:
Saving all css files in UTF-8. To do that I´ve added this at the very
beginning of each scss file:@charset "UTF-8";. That line is before
everything, even the comments.
Then, I´ve followed each and every recommendation told at this drupal post:
#12: to comment these lines: #Header append Content-Encoding gzip and #Header append Vary Accept-Encoding.
#15: To add these lines in settings.php: $conf['css_gzip_compression'] = FALSE; and this one $conf['js_gzip_compression'] = FALSE;.
#33: To manually delete files/default/css and files/default/js folders.
I would like to add, as a sidenote, that I´ve tried the @charset "UTF-8"; solution before, in my old shared host (I´ve a VPS now) in a Drupal 6 installation, and it worked.
I´ve run out of ideas, and just don´t know what I could try… any help is very much appreciated. Thanks!
Deleting the css files and adding them again (and clearing cache in the meantime) did the trick.
